If only the show actually used the proper interchangeable headcode signatures like in real life and the RWS (as well as the first 5 seasons, though not just at nighttime).

[@munipalsfanboything]

Well, they somewhat did. Seeing as in a single Season 1 promo image of Henry (Old Shape), Henry is pulling some coaches with a… ‘Perishable Goods’ headcode??? Keep in mind it was during the day.

[@RibbonRailProfuctions]

As an American, who’s been really getting into British steam locomotives, I’ve been learning the headcodes of BR . In TSW’s spirit of steam and the peak forest routes, you can put the correct headcodes on for what train your running. You can even put tail lamps on

I definitely understand why head codes were ignored a lot of the time in the model series, especially early on. I can't imagine how painful it might have been to try and make a modular setup like that. Theoretically I can see it being done with magnets but it would make every engine a lot more expensive. But what I don't understand is why they didn't do that for the CGI series. One of the big benefits is that you'd be able to do shots and characters that would be very difficult in model form, so why not take advantage of it more?

[@Dino-Jira]

Literally, same and the thought makes me so happy

[@kekofsodor4899]

Fun Fact: The white headlamps are supposed to have handles on them above the nub on top. The handle was present on Thomas' model in season 1 for some episodes and promotional material, but in other episodes and for the rest of the series the handle is gone. This is most probably because of Ringo Starr who during his time narrating the first season, had photos taken holding the original Thomas model. In one of the photos he holds Thomas up to his face and his nose presses up against the top of his headlamp. Being so small and thin, it wouldn't take much pressure to accidentally break the tiny lamp handle off. So the reason why all other white headlamp handles are missing for the entirety of the series, even into the CGI seasons, is Ringo's nose's fault.

[@FatHat-qi6hz]

Paxton's headcode is literally just express with a bit of (1) "uhh we get more laps." (2) "Eh just throw them on, oh, also make all the lights green and red." (1)"Well its is Christmas so. Oh well."

I like that they went to the effort to put lamps on the engines, and managed to sometimes getting it correct. It adds a nice degree of realism. Thanks for the video. I’ve build some trains in Lego and I’m convinced I’m mostly getting the lamps wrong. I have an E2, and I put the lamp in the centre to give it the shunter head code. I also have a GER F48 with a mineral lamp as it was a freight loco. Now that I think about it, I am getting it slightly right.

[@Ramtamtama]

Lamp in the centre is also light engine, whilst a light at the top only would be Thomas pulling Annie & Clarabel, as standardised in 1923 by the Railways Act 1921

[@TheOfficialArtOfAsh]

I'm kinda surprised the TV series didn't use the disc headcodes. (For anyone wondering, the disc headcodes are white discs fitted to an engine's lamp irons, like lamps. They were prominently used by the Southern Railway, and later British Railways.) Since the disc headcides are literally just white discs that could just be made of cardboard, they could've been an easy alternative for actual lamps. Oh yeah, I wanted to point out something: The lamp on the right lamp iron can be considered "light engine" in certain other railways like the Southern Railway.

[@Ramtamtama]

They were standardised in 1923, which made light engine bottom centre

[@Watermillfilms]

I thought disc headcodes on the SR where for designations rather than type of train. For example two white centred discs like this ( : )would mean to the West Country ( Exeter ) a down train from London. While the GWR had the standard lamp codes and destination number boards for passenger trains. For example 130 for the Cornish Rivera express London to Penzance.

[@BrentSudric]

You'd still need lamps for night running as the discs emit no light

[@thegoodmudkip3652]

I don't think they knew about headcodes tbh.

[@optiquemusic6204]

It is very interesting to learn about the lamp headcodes, didn’t thought about up to this point that each position of the lamp has a purpose as to why it’s there. It makes the show more grounded to real life!

Diesel 10's lights... i think thy are supposed to represent Ditch Lights. they're on most American based diesels, and they're close to the tracks to illuminate the line ahead. but that's just my thoughts on it.

[@lukemendel8197]

In the USA, Locomotive lamps are mainly for lighting up the track ahead.

[@SoldierFox1393]

Same thing with Canada as well, i dont understand why the UK thinks it's a good idea to not give them a cow catcher and just a standard headlight like Canada and the USA do. Maybe they just prefer to have the locomotive derail and cause more accidents and money if there was something on the track not to mention having non proper headlights(being sarcastic)

[@TrainsForNSWVlogs]

​@@SoldierFox1393it's because they inclosed the rail corridor with fences.

[@lordmalachi6]

​@@SoldierFox1393the tracks in the UK are all fenced in so nothing can (should) get on the tracks, unlike in the US/Canada. Also the idea with no headlights generally was that you can't stop in time anyway, so it's better to preserve the driver's "night sight". Plus the head codes are legitimately useful.

[@Jetthehawk1994]

Actually Diesel 10's lamps are what I think are ditch lights, lights that help the crew see closer to the tracks. But for aesthetics, Diesel 10's lamps were moved further down compared to his basis. If you look at a photo of a Class 42 in real life, they have the lamps situated at where I assume would be under his cheekbones.

[@clockwork3494]

I've known headcodes existed for the longest time but finding a concise list of accurate information on them has always been oddly difficult, so I really appreciate you going in to detail on them in this video. It's actually nice to know there was a headcode informational from the RWS too, not sure how I never found that but the more you know lol Definitely going to he using this information for my art in the future since I've always wanted to draw engines with their accurate headcodes, so thank you for making this.

[@Lampironstudios215]

Paxton's head code is what i like to call the "scare diesel into being a kinder engine"

[@DuckyLTD69]

For big diesel engines, They have discs. Back on the southern railway, they used white discs as headcodes and when British Railways came along, they put lights on the bogeys of their diesels but kept the southern discs for headcodes, later on the headcodes became redundant and while discs weren't a thing anymore, they, oddly enough, used letters? Funfact; BoCo, Bear, Bowler and Spamcan also have this arrangement, not 40152 [i think] because after the 1970's, discs weren't a thing anymore

[@thomasoates3003]

8:02 Early BR diesels were fitted with headcode disks which functioned in a similar manner to lamps, but the system was soon replaced with an alphanumeric display housed in an indicator box; 1M63, for example. The requirement to display a visible headcode was dropped in the early 1970s, and most headcode indicator boxes were plated over and lights fitted in their place. Diesel 10's headcode indicator box would sit roughly where his face is, hence why he lacks a lamp code.

Considering we have AEG now, I feel as though Awdry is likely looking down with disappointment seeing the legacy of his creation turned into a dumbed down shell of what it once was and what it was meant to be. Awdry said many a time that he wrote the RWS the way he did so both children and adults reading were entertained which I feel translated well to the early TVS too, AEG however has essentially flipped that premise on it's head and made it so unbearable that even the demographic it's supposed to appeal to hates it and wants the CGI version back.

Over here in American, railroads used lamp headcodes at night and different colored flags during the day. Again, they used to, as I doubt that is still a thing.

[@VivianMakin]

At my heritage railway, we use red flags on the back of the train during the day and at night we have hanging lighted lamps on both sides of the back car or caboose which have different color lenses on various sides. Our engines are from the 1930's through about the 1960's and do not have ditch lights...only standard headlights which are lit low beam when stationary and high beam when ready to move or moving. The steam engine (current getting its 1472 service) has marker lights on the top sides of the smokebox which light at night, but just as a heritage / historic railroad engine. All our engines pull both passengers and freight, including the steam engine.

I've honestly come rather passionate on that Thomas lamp shape. Though for the bigger scale models of him used for narrow gauge and Pack, it felt off. I also suspect them default having a lamp at their right, perhaps they saw like a person holding a flashlight in their right hand. Whiff also had one on his left in MIR. I actually like Salty's CGI lamp. Duchess' irons are actually more accurate to how they're shaped IRL, though her outer ones are white. Interesting that Arthur had white too. Of many things I'd wanna tweak to Rebecca's design, one would be a middle lamp. I'm often bugged when an engine has a right lamp but no iron visible on their left - mostly for Donald & Douglas. Interesting how S18 having ones like Samson and the Skarlo-fleet with just a left, while some like Gator and Ryan even have a middle one. For a couple of OCs I've attempted, one being a Urie G16 with a middle iron, and a Wheatley Y10 without the middle.

And I get why they stuck with the same Thomas position, maybe because they are struggling with putting the lamp on because you can see the wire. Must be a big pain in the butt to try to make the lambs work. And I agree with you that Stepney’s lamp should be on his lamp irons. Before I don’t even know what they’re called or what they’re used for. And then change in the dark, why would the writers put that in? And why would the writer say buffer and not lamp iron?

[@SouthernMaineFoamer]

As an American, I find headcodes weirdly interesting. Though, it’s hard to remember all of them. Also, most of our lamps (when it comes to steam locomotives) are either on the top or in the middle of the smoke box. However, the Union Pacific’s Big Boys and Challengers and a few streamlined locomotives sort of have a lamp in the middle on the bottom towards the cowcatcher/pilot. The headcode is basically pointless in the U.S. and North America in general. Instead, we have something called “Markers”. They aren’t used nowadays but back then every locomotive had them. They had 3 colors, white/yellow meant “Extra” (an example would be empty cars/wagon, a single locomotive, an excursion, etc.), green meant regular train (normal freight and passenger), and red meant end of the train. Cabooses had them as well. There are also a few type of specific lamps that are very familiar to North Americans but not to the rest of the world. One is called a mars or gyro light, it basically just sways around and side to side. The current one used is called a ditch light, it’s actually 2 lights and how it works is basically one flashes and then the other flashes as well. All diesel locomotives that are built nowadays are required to have them.

I think headcodes were thrown out the window just for the sake of the engines having a lamp, like a little spotlight for them. Most diesel engines like Mavis don't even need to have headcode lamps as they have little electric lamp boxes built onto her basis. I might be ignorant but I don't think other countries have headcodes so they just had a nice big spotlight lamp bolted onto them. Hell it's a pain to model headcodes onto model trains because lamps are usually glued onto our models and we haven't really got to the stage of magnetic headcodes!

[@sodorpro]

Nice video, I think one of the reasons as to why they stopped giving the engines head codes, aside from simply not caring, it's also because some of the head codes, like the light engine head code would obscure the face, and likely wanted things to be consistent. That and it being an easy way to recuse stock footage, at least in the model era, there's also well as possibly that promotional material had something to do with it, as most pics show the characters by themselves, so kids would likely be confused as to why the lamp is in a different position in the actual episodes, compared to the promos, where they would have the light engine head code. And then there's also the fact, in CGI, they would have to make individual renders of all the characters with different codes and with out the codes, so they could animate with workman applying the lamps to the engines. Which given the time constrains and animation budget they likely thought it wasn't worth doing.

An interesting thing to note is that headcodes are still a very important feature in today's railways, only they are letters instead of lamps now.

About you talking about the empty passenger head-code, one light on the top and one on both sides on the bottom, it's sort of like on modern American diesel locomotives, where they have headlights and a set of lights on the front and rear running boards known as ditch lights

[@asteroidrules]

Bash, Dash, Ferdinand, and Porter all had top-mounted headlights because they were also based on American prototypes. As head-codes were an exclusively British steam-era phenomenon, locomotives from the rest of the world almost always mounted a lamp either atop the smokebox or in the center of it, and the latter definitely wouldn't work in Thomas since that'd be dead center on their face. Logan is kind of an interesting case as his real life prototype had only one lamp iron, which corresponds to the ordinary passenger head-code despite being a shunter. Also given that head-codes are made possible by the fact that British locomotives didn't permanently mount their lamps, it could be assumed that the reason the lamps aren't always seen is because they're being taken off and stowed when not in use.

I think the reason so many of the lamps are on top of some of the characters is because with cars, American locomotives, and industrial engines (that don’t need to listen to headcodes because they don’t run on the main line or any branchlines) when you *add* a lamp you normally mount it on the place that’ll illuminate the tracks/road ahead the best; on the top. The lamp being on the side of the engine is because in my opinion it looks like somebody holding a flashlight. Marion’s lamp reminds me of attaching a flashlight to the side of a hard hat too. It makes sense design-wise to make the engines more anthropomorphic in any way you could, but I agree, it’s very off-putting at times. It’d be nice if every main cast engine had their own unique head code, to make it seem like they have free will over where they are, or that the crews just put lamps wherever they think is best/which is easiest to access when switching them out.

In the good ol' us of a, there are 3 places you'd put the "main" lamp either on the center of the running board, built/attached to the smokebox door, or on top of the smokebox. Since (afaik) we don't really have a "freight type" headlamp system, just a system for telling what schedule it's on with marker lights. Hope this helps.
