the only dual service loco on the NH was the FL9.
I used this as a guide, plus another site mentioning the Kaufmann Act. I don’t know of a city-wide ordinance in Chicago.

Steam engines of all kinds were designed and built in the late 1700’s, and development of the various competitors to Stephenson were all built in the very ealry 1800’s.

Well, I wasn’t intending to get into a detailed history of NH motive power, but you’re right, although the road operated 60 of them from 1956 until the PC merger. Several of the electrics also had AC/DC capability (catenary / 3rd rail operation). There were also two or three other locos that had dual capability installed by the road as an experiment, although I couldn’t find them in my reference just now.

AltonFan:
I know about the exclusion of steam locomotives from New York City, but this is the second time that mention was made of a Chicago ordinance banning steam locomotives in the city. I have trouble believing such a ban was enacted in Chicago because steam locomotives continued to be used within city limits at least as late as 1957, when the C&NW finally stopped running steam powered commuter trains. (And, IIRC, the occasional steam locomotive operated within city limits into the 1960s.)
OTOH, it is my understanding that smoke and/or fire concerns motivated the C&NW to purchase Ingersoll-Rand boxcab switchers in the 1920s.
So, does anybody have any concrete information on an anti-steam locomotive ordinance passed in Chicago?
As for steam being an “almost 18th century technology,” I’m not prepared to go that far, but by the time dieselization began in earnest, steam locomotive technology had just about reached its practical limits.

Here’s a 2006 MR Forum thread, Years of Steam and Diesel, where the primary thought was when steam conversion was completed to diesel.
Here’s the original questions…
Great response!!

I model pretty much the same era (1940s-50s) but the “transition” is a little different–the transition from electric locomotives to diesel-electric on a previously all-electric interurban, as well as the transition from a passenger railroad to a freight-only railroad. I’m kind of modeling “backwards in time”–first I only had diesels, then I added a couple of electric box motors, then a couple streetcars, and recently got a couple of interurban passenger cars. The prototype I model (Sacramento Northern) stopped carrying interurban passengers in 1941, stopped streetcars in 1946 and bought their first diesels the same year, dropped electric power in 1953, and abandoned most of the right-of-way I’m modeling by 1966. Now, admittedly I still have to install trolley poles and electric overhead, but I still run the freight motors and streetcars because, well, they’re fun. At some point I’ll hang overhead and evict the diesels once and for all…but if I model the 1946-1953 period, I can operate both!
