note - The vast bulk of my massive Web presence (over 485 pages) had been hosted by AT&T's WorldNet service since 30 May 1996; they dropped WorldNet service effective 31 Mar 2010 and I have been scrambling to transfer everything.  Everything's saved but all the links have to be changed, mostly by hand.  See my sbiii.com Transfer Page for any updates on this tedious process.

As you can plainly see, the DD1 was basically a standard 4-4-0, without cylinders or boiler, and with a BIG 650VDC electric motor sitting on the chassis, main-rodded to a jackshaft and thence to the running gear!

They were handsome brutes until 1939 when, for the New York World's Fair, they lost their "brows" as a nod to streamlining; more's the pity.

[Strasburg - put 'em back!]

Oh!   Look at that front door window,  Never noticed that change before!

HA!  Look at the road number in #3936's headlight numberboard!  Notice also that there is NO numberplate in #3998's headlight but that there is a tiny one hidden outboard just under the brow; another little detail easily overlooked (as I did).
