I am going to purchase Bachmann's HO Acela train set and probably add some additional Business Class cars to replicate the 6 car consist of the trains I traveled aboard last week between WashDC and Boston; round trip.

I noted that there are two types of Business Class cars offered by Bachmann that may be added and am confused about the difference. What is a Business Class "end" car compared to the "regular" Business Class car that comes with the set?

On the prototype trains I traveled there was a foward loco, then two Business Class cars forward - a Cafe car - two Buisness Class cars and a 1st Class car at the "end" - followed by a loco.

Thanx.
