These units are moved with the brakes isolated. The wagons are there to provide brake force . The locomotive doesn’t operate the brakes on these units. Brake continuity is provided by running air lines through the units being dragged, you can see the hose feed through the cab window. Either the brakes on the 777 have not been isolated or the parking brake has somehow applied.
Interesting watching the driver check the brakes - they’re discs so he needs to get inside of the wheels, which probably requires an isolation of the 3rd rail. As for the wheels with dragging brakes - they’re gonna need replacement wheel sets. Wonder if the train had a 777 qualified fitter or driver as part of the crew make up?
Hmm, 🤔 the brakes are supposed to be isolated as they're different from regular loco-hauled train brakes, that's why all those wagons are there to provide brake force. Looks like someone (probably when it was parked overnight) left a parking brake on 😖
The brakes on the 777 Are exactly the same as the 66 Air brakes if the brakes were isolated the barrier wagons would be on the rear of the 777 Because if the brake was isolated and the 777 became detected the 777 could runaway What happened here was the driver never pressed the brake over charge button hence dragging brakes
@@susansmith3568 Sorry, you are incorrect. 777s are transported with the brakes isolated and through piped. On many videos you can see a temporary brake pipe that goes through the cab side window, it runs the length of the train and out the other end to connect to the trailing translator and brake force wagons. They've been transported like that from the very beginning. I've seen it first hand when the train reverses at Sandhills station to access Kirkdale depot.
Why is it comedy gold? 777s have tread brakes, not inboard discs, so it is possible to see if the brakes have released from the four foot. I was watching a 777 at Hamilton Square the other day, even from the opposite platform (Ellesmere Port/ Chester platform) it's possible to watch the brakes release. Did you expect him to crawl underneath it?
Additional brake force. The 777s are hauled with the brakes isolated and through piped. There is a temporary brake pipe that runs the length of the unit to connect with the trailing translator and brake force wagons. That way the driver has control of the brake on the wagons, and should the consist separate, the unbraked 777 is sandwiched between braked vehicles or the locomotive depending on the formation.
2024 and we are still moving units around "swinging" in the breeze with brake force runners because of stupid compatibility issues with coupling and brake systems. Under BR everything was compatible bar a few exceptions with either buckeye and/or screwlink and buffers. Not only that these moves don't even have a second man on them to assist with moments like this. The modern railway is an absolute clown show.

Yep thats how we moved the Heathrow Express 332s to Willesden for tyre turning. A real pain in the A running that through pipe.
I bet that' caused a lot of damage !! wheel flats and everything ! Expensive !
About time they come up with silent camera shutters.
Indeedy I agree 😅
Fantastic video, nice captures. :)
Cheers!

They'll check it at Walton or something where there based where the proper fitters are.
777s are tread (and regen) braked; no discs.
That’s a fairly long train
@@karlbbb really? I thought the coded brake (Westcode) was pretty much de facto on UK trains nowadays - but we learn something new every day.
Are you an expert full time or just on this video ?
Right place right time 👍
Indeedy!
LUCKY! 😮 Unlucky for the 777! 😂
Yep! At first I thought it was the 66 thrashing up that little incline until it got closer it was at the side of the train.
@@andrewroberts1376 I was at school when it ran, and I thought it was a 92!!!! ☹️
@@SSccaanniiaa wouldn't be a 92 as DB 92s can't run 3rd rail anymore. Unless they hired a Gbrf one they could but they won't.
@@andrewroberts1376 I know 🫤
Hopefully the next drag is soon! 😄
@@SSccaanniiaa that'll be the 555s they go early evening via Tonbridge the 777s are Finnished.
Amazing, when it did pass by the didnt seem to be any flats on the wheels. Maybe a traction motor burnout, but it wasnt under power??
I assume the wagons at each end are match wagons????
Looks like there was no damage to the wheelsets judging by the speed he was going through the last station
It was fine after Sevington Loop yes but still needs to be checked at there Merseyrail depot.

The Driver stood in the 4 foot checking the brakes-comedy gold.
@@jimperkins2446 how do you know?, did you take the Call from the Driver?, divvy.

I’m guessing he had a line block, from the signaller. Could of been the signaller that reported it to the driver
Well that's one unit needs a wheel grind, why so many barrier wagons? 😊 Good video,
For Air flow and braking. Thanks!

@@neilcrawford8303 thank you very informative, I was wondering why so many wagons in the Train 👍

Agreed. I have seen a second man on this before but sandly not this time.
Was the first unit MerseyRail and the second one Tyne and Wear Metro?
First one Merseyrail (777), second one is two T&W Metro sets (555).
What was the flash on the locos front bogie at 1:25
Bug. It went across the screen
what were the other units at the rear, and were they of to.
There for Tyne and Wear metro they're off to York.
@@andrewroberts1376 oh right thanks.
Nice new trains, not like those ugly Azuma's. Nice E.M.D. like the
SD 40-2
Better to take photos than try and alert the Driver eh lads..
I did wave at him aswell but he slowed down before the station anyway
Good job. Continue ride with blocked brakes is dangerous. 😮

Two guys stopped train in Poland to avoid derailment.
And the driver did not see anything ???????
We don't have wing mirrors.
@@michaeloconnor7849 Looking out of the window is no option ???
@@class77sncb not in my cab as it has no drop lights and the door interlocks kick in at 7 mph.
Ohh, not so good!
Yep indeed not good!
How can the Driver check the brakes on his own > Ridiculous! One man drives the other stands beside the to check the wheels are turning !
Normally this service is second man but not this time.
