Lee was absolutely correct.  That is what the loco was made for. Whether it is 
absolutely a prototype  or not.
The founder told me what he had in mind.  He was following some NYC or a New 
England loco style.

His switcher was somewhat PRR.     Modeling in S  (manufacturing) was a bit 
loose in those days.  It was before the rivet ,and bolt thread counters were 
not as passionet as they are today.

  Lee I beg to differ;



  A Suburban is a tank engine with very specific attributes.  
  1)  Double Ended for ROAD service, this means having full pilots at both ends
  2)  Fast, Able to do high speed quickly
  3)  High fuel water capacity hence the 4 wheel truck REAR truck.


  Only 3 designs I know of;  a 2-4-4, several 4-6-4 and the biggest a 4-6-6.  
All the suburban types but the one were 4-6-0 types modified with a 4 or 6 
wheel "rear" truck to hold the tanks.  The other was a 2-4-0 so modified, which 
was the prototype for the Rexx engine.


  I believe you are referring to what is called a tank switcher usually with a 
2 wheel 'trailing' truck.  Porter and others also made a "plantation" engine.  
A 4 wheel rear truck as on a Suburban but low drivered for pull not speed.  
There were some narrow gauge tank engines also double ended, in fact advertised 
as such so as not needing turntables, but not built for speed and usually with 
a trailing truck not a rear truck.


  Hope this clears things,

  BTW:  The closest to a double engined 2 facer (44, 45 tonner et al) in a 
steam engine would be a Farley:)

    A Suburban is not a double ended engine like a 44 tonner, but a usually 
smaller engine with the coal and water bunker being a part of the back of the 
engine and supported by the back truck. By the way, the Rex engine bearing this 
configuration has been called a Suburban for over forty years that I know of, 
right or wrong. Another "by the way", a Rex Suburban is a 2-4-4, not a 4-4-2.
