If it helps, Maplewood, Hillside, and Chatham are also places in California. 

 

Imposters and cheap imitations!  

So speaks a Jersey boy!

Have seen mentioned herein that... "three passanger cars - 2421, 2422 and 2423. These being the Maplewood, Chatham and Hillside cars with silver roofs" were part of what was intended for the 2033 engines. 

The 2033 being a Union Pacific engine, why would East Coast cars be part of it as a 'set'?

thanks.
