The Delic's activities are on East Coast Main line, we already have it. Getting this class 55 working on this line would make sense to me. You could further expand this and introduce the DP1 which was the first prototype before the 55 was put into service. You can't go wrong with this in my opinion. And a green variant which would represent one that's part of the preservation society, that one could differ from a model replicated based on it's time in service, so the engine sounds would be diffrent like with the 47.
Yes, this has been suggested on multiple occasions, so hopefully we will see DTG or a third party pick this up in the near future. It would take TSW to another level - if done to a high standard of course
I've had the delic in their Railworks at the time with Armstrong Powerhouse enhancement which overhawled the sound and added dynamic smoke. Truly an incredible sight. The locomotive could even be added to NTP and of course the "retirement village" line i call it or west somerset railway doing tours and other mischef of course. If done right, the locomotive could really bring alot of joy, people will not hesitate to get the package.
