4 (Crescent) + 4 (Star) + 4 (Meteor) + 3 (LSL) + 4 (Cardinal according to some!) = 19
+ 20% shop count of 4 = 23
+ 1 protect each in Miami, New Orleans, Chicago + 2 protect in NY == 28
26 is not sufficient for expansion It's not even the number you want for the existing trains, really.
If the daily Cardinal only takes 3 and you only have 1 protect in NY you have exactly enough.
Anything further (such as the suggested branch of the Crescent to Fort Worth) is stealing from another train (most likely the Star, which may never get its dining car back).
The Heritage cars are beyond unmaintainable at this point and must be retired. But I do think that 26 dining cars isn't enough; Amtrak needs to get a few extras in case of wrecks, at least.
