Will the new trains follow the modern NR pattern of having one incandescent highbeam light and one or more LED marker lights on the front of the train?

As far as I'm aware LUL trains are not bound by NR standards - we like to do it our own way thank you! ;D ;D (waits for prjb to prove me wrong). Whatever next?, Yellow fronts ;D ;D

We will not be following NR on this, but as our trains travel over their metals we would need a derogation to the Rail Group Standards. Yellow fronts? Never!

ISTR that the yellow fronts rule wasn't that they had to be yellow, but the same colour across that particular fleet. Therefore as long as that practice is maintained you should be compliant with the standard and hence not require a concession.
An example of compliance is achieved for other LU stocks is that number of middle DMs of 1972 stock have half-red fronts in case they have to work on their own as a 4 car on the NR parts of the Bakerloo.

AFAIK the middle cabs that are red on 72 MkII are double ended units fitted with OPO equipment at both ends. This allows the units to be used as either north or south end for flexibility, just as some 'A' Stock units are the same.
The derogation to RGS I was refering to here though was for the headlights, thats assuming that the NR arrangement is part of their standards and not just custom and practice. I am the first to admit that I know very little about NR.

While lights are being mentioned: will the lights within the cars be tubes as now, or LEDs? (sorry if this has been covered before). They would probably last longer and would likely lower the electricity bill for LU. Emergency lights might be able to last longer on the battery too. Or are they too expensive and complicated to try at the moment?

They will be tubes but off the top of my head I cannot remeber the type/voltage etc.

Will they have diffusers like the ones in the refurbished D stock?

Most definately, although the final design has not yet been decided upon. I will go on the record here and state that IMHO BTUK are very much 'on the ball' with their lighting solutions. I think the 'D' Stock lighting is great and was also very pleased with how the 09ts mock up looked in this area.

The 3 car units always work on the north end and 4 car always on the south end, the north end cab on the 4 car isn't used.

The only reason why the 4-car double-ended 1972TS's north-end DM has the red front is so that it can operate alone on NR metals; if it didn't have the red front it would not be permitted to lead the train.

The 4 car doesn't have a red front on the middle cab,it's grey.

I recall standing next to a now retired HMRI inspector, who was trying to persuade me and my LU colleagues that we had to have yellow fronts. We had arranged a test for him which proved that the yellow front didn't necessarily provide a better visual warning than the red under all circumstances and that the best warning was from bright headlights. We won.

I pretty certain there is at least one unit which has the half red front on the otherwise unpainted end... This, i believe, was so this it could, as stated, run on NR metals alone. It was done as far as I recollect so that it could transfer another unit elsewhere, primarily Acton works, and then return to depot by it's self.
