Not enough here & I think any slight difference impacts on the certificate.Wonder why the 3 cars are not approved at same time, are they that radically different just missing a car an an engine or two?

I would guess the power to weight ratio being lower will change the performance enough to require separate testing.Wonder why the 3 cars are not approved at same time, are they that radically different just missing a car an an engine or two?
Theoretically, but then you wouldn't have thought it'd take 2 years from the 345 entry into service to the 710s being ready, yet it certainly happened.Isn't that because bombardiers resources have been focused on getting the class 710 units approved which are mildly similar to the 720s?
Surely it won't take very long before the 720s are approved as all the leg work has now been done with the 710s?
True, but it was explained to me that there was a huge difference in the software. And although they look similar mechanically and probably are..the 710 software is completely new and very buggy. And so i understand the 720 software is very similar to the 710 setup. But yes..it could take another 2 years...but i hope that it won't.Theoretically, but then you wouldn't have thought it'd take 2 years from the 345 entry into service to the 710s being ready, yet it certainly happened.
Just passed Dollands Moor and there’s a GA delivery attached to a red 66. Couldn’t ID either.
Indeed, there are far fewer changes this time around, but the units are still not exactly identical by any means.True, but it was explained to me that there was a huge difference in the software.

Probably 66001. It seems only locos without the swing buckeye couplers can be used to haul the units.A red 66? Thats odd, 66002 is normally roistered for these drags, and she's still in ex-EWS
Platforms 5 and 6 are both 6 carriage, so even with the power car, both the new 755's should fit, and both look wired:Will the 754s be using their bi-mode capability wherever possible - eg. on Norwich-Cambridge, switch over at Ely? (thinks: are the north-facing bays at Cambridge wired, and is P5 long enough now they've built the footbridge?)
There have been quite a few discussions about that in this thread already, but I think the general consensus will be no unless the trains are actually covering some distance on electric power. If it's just for a station throat it doesn't seem like they will bother, other than maybe potentially Stansted, I'm not sure about that one.Will the 754s be using their bi-mode capability wherever possible - eg. on Norwich-Cambridge, switch over at Ely?

They will work on electric mode whenever possible. Nothing has been confirmed on traction change whilst on the move but from what I've heard it is unlikely. Time will tell.Ely to Cambridge is still around 10-15 mins, then as you say the extension to Stansted adds on another 30 mins.
Would seem silly if they don't especially as the small fuel tanks are well documented.
Actually if they go to Stansted don't they have to be under Electric? The short platform is taken up by snoozing XC units, could sit off the end of one of the long platform I guess as it often does now.
They won't stable there but they'll be maintained there - I think once a day(?) one of the Norwich units swaps to be a Stansted unit so it can go to Norwich for maintenance, or was it once a week?question regarding the 745/1. Where will they be based, surely Norwich is too out of the way for the Stansted route
Probably stable at Orient Way and Bishops Stortfordquestion regarding the 745/1. Where will they be based, surely Norwich is too out of the way for the Stansted route
I was told by a local (Norwich) driver that they might have to switch to electric mode during their layovers at Norwich to keep the systems running without wasting fuel. Also, refuelling might be required part-way on some diagrams.They will work on electric mode whenever possible.

As long as the switch is easy enough to do I'm glad that's the case, it only makes sense.I was told by a local (Norwich) driver that they might have to switch to electric mode during their layovers at Norwich to keep the systems running without wasting fuel. Also, refuelling might be required part-way on some diagrams.
Possibly because the power module can be removed to create a different unit type? Or is it because the individual coaches cannot be run in isolation due to only having one (and a half) bogie because of their articulation?
Would make sense. Quite a simple changeover between modes.I was told by a local (Norwich) driver that they might have to switch to electric mode during their layovers at Norwich to keep the systems running without wasting fuel. Also, refuelling might be required part-way on some diagrams.

I didn’t know about that.It’s not your second though, a lot of french units are articulated and they don’t have a 90 registration.
Yes of course.Would they not change power at Ely whilst stopped?
