I was a Class I U. S. locomotive engineer. I can attest to the complexity of air brakes. Air brake theory was an entire week of classroom training at engine school in the early 2000s and probably still is.

[@lorenzoromano_original]

Yup can confirm, I'm currently training as a locomotive engineer, we spent a whole week on air brakes, and even if we have moved on, every time someone names the word brakes by chance we do a complete review, since the complexity and importance of the topic.

I just hope a pair can be preserved, in the UK, one of each class is preserved but only a few in regular working order to pull excursions and other special trains .I know the Swiss and Germany also has preserved many locos, 😊 by public demand and appreciation

[@kristenburnout1]

Awesome video, Sandro! I really love these old Swiss electric locomotives, especially because we have several locomotives here in Norway that were based on Swiss designs. Our first "proper" electric locomotive, the NSB class El 11, was directly based on this Re 425, but built by local companies. Following this, the stronger El 13 and El 14 were all "Swiss" locomotives built locally in Norway. The most interesting of these is the 6900 horsepower El 14, a real beast based on the Ae 6/6 "Gotthard locomotive" that is still running freight trains across the mountains to this day. (Although sadly they are really run into the ground compared to the relatively pristine conditions you keep your older locomotives in!) We also have a local variant of the Re 460, called the El 18, as well as an ever increasing fleet of FLIRT trains built by Stadler. :)

[@nimaforoughi7266]

Not to mention all the steam locomotives. SLM have a history of delivering to Norway dating back to the 1800s. In the NJK-database you'll find many examples, a large number of these being built for a narrow gauge of 1067mm.

Sad to see these true workhorses go. Many years ago I spent 5 days in a holiday home in the spiral just below Blausee-Mitholz station, and it was awesome to see the trains at 3 levels across the windows. The Re4/4 made up 80% of all trains then, completed by the Re465 but also still some Ae4/4 I and even the historic Be6/8 which double headed with a Re465 for a train, which also had a Re4/4 pushing.

[@luckyluke5150]

Nice Video, i like it! Small correction: "Schleuderbremse" is comparable with anti-slip regulation (ASR, prevents a wheel from slipping when accelerating). You said it's like ABS. There is a system for trains comparable with the ABS, called "Gleitschutz" (prevents a wheel from blocking when braking), which i am not sure if the loco has one. Most of the passenger carriages have one.

[@JoJoModding]

It's also not called "tension," it's called "voltage." Tension is purely mechanical, voltage is electrical. If you apply tension to a motor, this means you are putting the motor in a hydraulic press, or (in German) "spannt den Motor." This is not what is meant, you mean "apply a voltage," i.e. "Spannung anlegen"

[@JohnGeorgeBauerBuis]

@@JoJoModdingI have heard of high voltage being called high tension, but it seems to be a European thing (including the UK).

[@mutzbunny]

@@JohnGeorgeBauerBuis it probably is always a translation fault because voltage in german means "spannung" and tension in german means "spannung" so if you just google translate it, you probably get the wrong answer. pretty sure thats whats going on

[@tookitogo]

@@JoJoModdingWe used to say “tension” for voltage in the past, but as others said, the term survives only in the term “high tension” (like power lines).

[@tookitogo]

@@mutzbunnyActually it’d be translation error. ;) (A fault means more like a breakdown, whereas an error is a mistake. In German, both are “Fehler”, although I suppose you could call a fault a “Panne” or “Defekt”.)

[@nimaforoughi7266]

Are they planning on sending a few of these to BLS Historische Fahrzeugflotte and to Verkehrshus Luzern? Hopefully they will be seen on the rail in the future too. I was, unbeknownst to me, taking pictures of some of the last regular Brownie services along the Thunersee just over 10 years ago. The brownies were so common they seemed immortal, but alas, here we are.

[@robertfussey7799]

Really good footage and technical detail. As a locomotive engineer myself, it was interesting for me to note that the brake gear was of Davies and Metcalfe manufacture, much used in British railway locomotives, and superior (in my opinion) to Westinghouse equipment.

[@wewillrockyou1986]

I wonder if someone somewhere has one of the traction relay blocks detached from the transformer so you could film the switches themselves in action. I love my power electronics more than anyone but there's a certain magic about seeing the contactors fly in and out as the power is applied.

[@inothome]

I really hope there is one saved or will be at least one saved for a museum or for history. I didn't understand the air with no sand, what does that do? And in my limited locomotive electrical repairs, the older traction control I am familiar with is triggered when the motor current drops, indicating less torque applied. Not when the current goes up as was mentioned, but maybe lost in translation. Awesome video as always and looking forward to the brake video. Curious to how similar it is to N. American type WABCO brakes. If you are curious to as what is going on in the load switch, look up transformer LTC (load tap changer) videos. There are different styles, but all do the same basic function by changing taps. Some are really cool looking too. Being a substation / generation plant electrician I've rebuilt a few throughout the years.

[@sandro-here]

To answer the "sander", this is the thing that cleans the rail in front of the locomotive. The high pressured air stream blows away water, leafs etc, enhancing adhesion. Regarding the skidding protection, I did understand that the current goes up indeed (as the affected axle spins very quickly when it slips). But then, I talked to an engineer (driver), not an engineer (developer). Damn, that word is truly broken in English, how can it be the same for both? Thank you for your compliments and recommendations!

[@inothome]

@@sandro-here OK, so it cleans the rail. I can see that with leaves and such and I guess it works for there, for 60 years at least. As far as slipping, it slips when it loses traction and the traction is what's giving it the load. Less load, less current. But they may be comparing it to the axle that still has traction, you would expect to see the current go up on that axle when the other axle(s) lose tractive effort. Forgot to add before, I work on a lot of ABB high voltage equipment and have only seen a few BBC pieces of equipment here and there, very rare. So cool to see the BBC train before they merged to become ABB. There is a lot of older ASEA electrical equipment in the US though. And I hear ya on English!!! Pain in the ass for native English speakers too. Don't forget to take a break after you check the brakes. Wind the watch before the wind blows. Add flour to the mix and watch the flower grow. After you read the paper you can say you read the paper. It goes on and on.... Insanity!

[@mutzbunny]

the 420 is not as old as the 425

[@pivkaaa]

Today, recuperation (electricity return to the line) is probably a question of a software update :) Still Im surprised that it is not worth the upgrade.. Maybe the motors in brake mode have some crazy parameters that are difficult to change to the line parameters ?

[@sandro-here]

This is 1960s tech. The "update" would be to replace the huge resistors on the roof by some very expensive electronics.

[@denitzaroussinova3529]

The company that made the gondola used older Poma grips instead of their own grip. I'm not sure what the company is though. It is also one of the last 4 seater gondolas still operating (1988). It uses only 1 bullwheel at the middle station which is connected to the only motor. It also has 2 strangely shaped pylons right after the bottom and middle stations. There is also just 1 conveyor belt instead of 2 to correct the distances. I think it runs on DC. Also, in just a few years, the ropeway will be replaced.

[@sandro-here]

Probably not economical. The Re 465 are getting freed up due to self-propelling trains replacing older person trains, so it seems logical to se them I guess.

[@juliuseskola1281]

I wonder if there’s any more info on the electrics of this locomotive somewhere. Even the German Wikipedia article seems pretty bald. Does it use an AC motor or a DC motor? What AC motor type ☺️

[@mutzbunny]

It uses a 1Phase AC motor, directly fed from the Transformer via the so called "step switch" which essentially is a Tap changer of the transformer. the schematic is plain simple 15KV in, transformer, step switch, direction swtich, main power contactor (if that one gets stuck you get a stepper switch explosion), motor (I might be wrong on this one, but im like 95% sure thats how it is)

3:32 - that would be PASSENGER train... I guess that LKW/ PKW naming convention just kicked in...? ;-) Also, I'd consider changing the intro shooting angle - for me, a viewer, it feels as if I were a rabbit (or a rat) in a hole being greeted by a hunting dog (cat)... Why not "eye level" camera position? 5:21 - "Spannung" is indeed "tension", but "voltage" would be more accurate translation in the context of "electricity" (or "electrical potential difference") - so "carrying a current of 15 kV voltage, AC at 16 POINT 7 Hz". Again, not "wrong", but then not quite "right" either; the "dot" is the mark, when placed at the end of a sentence is called "full stop", when used as decimal point then it is, well, a point ;-) Now, I know this is "about trains and locos", not "about English", but using language patterns and phraseology of foreign language when speaking it does help to convey the message, I'd say. Also, I'm not going to point all of these "carbon copy expressions" as I'm mostly skipping through this video (so I will surely miss most of them) and at any rate I'm not going to make fun of this - that earlier remark was meant merely to "point an issue" (or "provide a feedback"), and nothing more. Also, I'm not a native English speaker either, so I do understand how it works, and I do make, sometimes, similar mistakes. Cheers!
