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, TCC:} BTW: The closest to a double engined 2 facer (44, 45 tonner et al) in a steam engine would be a Farley:) On Apr 7, 2013, at 10:35 AM, [email protected] wrote: > > 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.
