Abellio Greater Anglia Class 755s (Regional Trains)

[jammmmmsssssss]

Change-Over Protection, a GPS based system on the 755s to ensure pantographs are lowered when driving towards the end of OLE.

I always wondered what would happen if it had the pan up going towards bury at haughley and coldham lane junctions

What does COP stand for here? And why would ASDO need to be overridden?


But I imagine the added diesel consumption when idling would be enough to reduce their range and require more frequent refuelling - though this may not be a problem depending on how often they are refuelled. As for raising at speed, correct me if I'm wrong, but doesn't that require upgrades to OHLE? If so, it may just be better to extend the line until the end of the platform. Of course none of this is solving Cambridge platform 5, which is the main issue as platforms 3 and 4 are most often used at Ipswich anyway.

Yes sorry, shouldn't assume everyone knows what COP stands for.

We have designated areas where we can raise them at up to 100mph.

ASDO if may have to be overidden in the example given as platform q at Ipswich would not accommodate two 755/4s. Drivers wouldn't accept that responsibility except in an emergency,

 

[jammmmmsssssss]

Theoretically could a 2 x 755/3 go to the stops with the front unit on diesel or would be add a layer of complexity rendering it not worthwhile?

But what would be the point of this entire thing anyway as the back 2 coaches won't be platformed at most stations

Been done many times at locations such as this, Ely North & Trowse. Train comes to a stand before running out of wire. Driver starts diesels and continues

Lol I thought it would just rip the wires down but they've put a system in

Absolutely that’s what COP is. Running off the wires doesn’t rip them down mate.

Yeah I knew it probably didn't but it was quite cool to imagine

Cool?? That’s a strange word for something that causes so much chaos & disruption.

Sorry used the wrong word there. Interesting, I guess, like how this

is interesting to watch

No worries. In the early 755 days I ballsed up several times. All good fun & a lesson or four learned.

Lol I did see that a bit when I read the early pages of this thread
