75mph on the GCR with D123

[@SYKAROST]

I've actually driven D123 at those speeds with expresses on the NE/SW route as a fireman ...... but it was in 1964 lol. Those wonderful memories never fade!!

[@SouthernSpotting34050]

So you DROVE a DIESEL as a FIREMAN??? Doesn't quite add up there pal

[@michaeljohn7262]

Shows how good the GCRs track is.

[@m_l_hill]

All my fillings come loose just watching that.

[@STEVE40012]

Yes "Dr Ben" has it right and with 75mph operation for a Diesel the operation is tightly controlled on a small portion of the line under a full possession.

[@Mr.insect47555]

Had a drive of this peak it’s got some grunt when wide open

[@kevvynolan8753]

demonstration runs with mk1 stock, with various loco classes at gcr would be worth seeing! riding even better!

[@benjiw1717]

@andysim232 GCR Is allowed to test steam at 60mph, and diesel at 75mph

[@bombadilian]

Excellent! Bet that was the first time it'd done that sort of speed for a long time.

[@angeltransportpjects]

This is one for inclusion in a 'TRAINZ Rail Simulator 2012' Scenario! I don't think the GCR exists yet for this PC programme but a few other Heritage Routes are along with this type of wagon (freeware by Eldavo) and the Class 45 in BR Green from the Download Station. Fascinating to see this on video so thank you very much for sharing / posting!

[@SteamboatWilley]

That'll blow away the cobwebs!

[@johngibson4641]

That's crackalackin along isnt it. So whats the deal with the slip carriages done for ? Awesome video by the way. Cheers from John in Australia

[@andysim232]

i thought Tornado was tested on that line at 75mph too. Maybe I miss read

[@Rickstew86]

Cracking video! The line soon disappears travelling at that speed!

[@penybontshed]

Now if it was doing 90 with 9 Blue and Grey Mark 2s that would be really nice!!! Especially if the Turbo was chirping Ah memories!!

[@davidpladgeman1462]

The special coupling was a wonder of engineering

[@david103857]

Wow! That's amazing - shame they can't do that with passengers riding behind.

[@vikingsmb]

problem is they have the stupid 25mph limit

[@bennickss]

@@vikingsmb Not in the case of the GCR, they can go up to 50mph

[@thetrainsrock]

@@bennickss thats a good joke

[@iantrack]

Superb remember these on the Northolt rubbish trains powering through West Ruislip

[@tobys_transport_videos]

Now for Slip Coach operation!!!! I reckon GCR would be the place to do it! Roll on GCR and GCRN being *ONE* railway again!!

[@GaryNumeroUno]

I guess its a modern day slip coach!

[@pauledstock225]

Seems like all the commenters know what is going on here, so I'll ask my question and hope to get an answer. I understand "brake test," but why was the following unit detached from the loco? And, when he applies brakes, doesn't the detached unit slam into the rear of the loco? Thanks for the help. (BTW...I have followed big trucks on winding roads down the side mountains here in the States, and have smelled their brake shoes heating up, and I swear when the driver here hit the brakes, I started smelling hot brakes. It's funny what the brain will do as we watch something like this.) Great video...I like videos that show the driver and what he is doing.

[@tombaker1222]

Paul Edstock When the air pressure or vacuum in a brake system is destroyed, the brakes are applied. So although this is simulated, when they detach the wagon on the back the brakes should apply fully. The test shows what would happen if the worst happened on the mainline and a consist split - they're testing the wagon's brakes in effect. That's also why it doesn't slam into the back of the loco further down the line!

[@pauledstock225]

Thx Tom.

[@thetrainsrock]

@@tombaker1222 that type of wagon doesn't have vac brakes. It's got air brakes only

[@JintySteam1]

WOW! nice, did D123 have to be modified for that (the uncoupling part) nice to get a bit of speed out of the loco, i like the switch to the track side.

[@kwinuytin]

Great video

[@leonperry123]

Ride looks a bit rough

[@MG06ZT]

Great stuff!

[@dylansworld8904]

Nice
