A bit of news worth mentioning has been given by Tony today. I look forward to leaving sidings ECS and then having to change ends to continue the working 
A Pendolino is in beta at present. There's another post on this forum about it.
There will be a new release of NWM in June. It has new diagrams for classes 31, 37/4, 37/9, 47, 66, HST, Voyager, Pendolino (and if it's ready, the 50). DMUs 153, 156, 158, 170 and EMUs 321, 323. This should cover most BVE4 traction.
The routes are totally revised with new objects, and new sidings at Whitminster and Brookfield. Some diagrams have a reversal procedure. This feature allows the Blackbrook branch to be driven in both directions. There are also some diagrams that now leave the carriage sidings as an ECS working, and then reverse to continue the diagram.
At present track layouts are still being updated and I expect this to take another two months.
Hope my RA information was of some use to you.
