@BradshawLSWR@AndyRoden1@Modern_Railways Yes, I think I wrote about that idea some years ago but I imagine the new bi mode locomotives will make that harder to justify. Still a good plan though.
@PacerClara Under BR the role of thumb was that 5 vehicles was the break point where loco haulage is cheaper. When I worked for Porterbrook I updated the calculation and got just over 5, so in event 6. But it is not as simple as that, operational convenience and reliability apply as well.
@Captain_Deltic @RailwayQueen @InnoTrans I was a bit intimidated by one very attractive woman who I thought might just refer me to an engineer, but she turned out to be very helpful and knowledgeable, needing no backup. If you really want to pull people in at Innotrans you need seats, the ultimate object of desire.
