So it sounds like some cafe improvements could easily be done for the 'shorter rides' like NYP to DC. That would help. Bigger selection would as well. But what about much longer rides like NYP to Montreal (once that reopens)? You need a kids menu, and availability of 'real' meals. Dining cars would make sense on a train like that, IMHO.
>>The 3 crew members share duties , ( train manager (conductor) and 2 attendants) so there is someone avaliable to do this without shutting the cafe.<<
The unions would never let you get away with that in the US!
