Dave V. has the right idea...there was a cement/pagoda tile design standard on many, many, New Haven towers (Signal Stations)...the one in Groton, SS119 was one of them...SS71 in Devon and several towers of this design still stand...and Dave is correct that this design is made in N, by N Scale Architect....I'm not sure about HO either....
There were many other towers on the New Haven you can model without scratchbuilding, Josh...Old Saybrook and several other locations were wooden towers and resemble some of the Walthers kits. Old Saybrook stood until the late 1990's...Kingston RI is still there but move back from the tracks.

Also depends on the railroad. Some railroads used a relatively standard size and design (I'm thinking New Haven, C&O, and DL&W to name a few). Others, like the Pennsylvania RR, a.k.a., The Standard Railroad of the World (please note the irony), had any number of sizes and designs for interlocking towers, from the massive Zoo tower in Philly (the size of an office building) to some single-story shacks like Buttonwood, and a hundred in between. Many shared a common design but had different footprints, like ALTO, ROCKVILLE, LEWIS, BANKS, VIEW, etc.
If you're up in Connecticut, you're likely to see plenty of former NYNH&H towers that are relatively standard in size and style. N Scale Architect makes them in N; not sure about HO.
