Must admit I am not a fan of running "units" much prefer loco hauled. But with the Pendolino and Azuma being used so much these days I fear loco hauled on Passengers will be few and far between on the 'modern railway'
More British zombie transport?: Really seen enough of that. Especially those obliged 1 minute stops get really boring, with the same 'faces' on all routes, USA included.. Some specific freight hauling, more variety other than oil and coal,etc. Rocky mountains route? Some mail-train free roam stuff? Derailment equipment? Steam trains from the early 1900s or before?
