Does anyone know if the R17s were all powered A units, or married pairs, with A power and B dummy trailors. What was the wheelbase?
They were all singles. 36’0’’ truck centers, 6’10’’ between axle centers in each truck.

Note that a married pair does not usually mean that one car is unpowered, only that two cars must be operated together as appliances are generally distributed between the two.
I don’t think any trailers were built for the NYC Subway after 1930.
You even included the blueprint! Thanks allot! I asked this question because Im getting a 4 car HO MTH R17 train set. There’s a general rule that I’ve applied to my modeling skills, “NO DUMMIES ALLOWED!” If the prototype is AB I will power my models AB if they’re all powered, then all my cars will be powered with DCC decoders too! Therefore my models will feel like the real thing. I think the MTH models are one powered and 3 dummy so I will be ordering parts for motoring or I will order more power cars.
No problem. See if you can get in touch with the Lion after he returns in September as he knows more about the Subway than I do.
Married pair on the New York subway system, the LIRR, and Metro North means cabs only at one end of each car, batteries, motor-generator or transformer and inverter, and possibly compressor , just one to both cars, equipment distributed for weight balance.
Are there single ended cars?
I don’t know about the NYC Subway, but the PATH system between NJ & NY does have powered cars without cabs, kind of like a “B” unit with diesel locomotives. They are run as triple units cab-no cab-cab
In a sense, married pairs are composed of two single-ended cars run back-to-back. In some casas couplers are used but in many cases only drawbars. On Metro North and LIRR, there are no separate single-ended cars. I believe currently the only single cars are some on Metro North in New Haven service, dual-mode, and they are double-ended. Metro=North was considering some three-car units with “blind” center motor cars, triplexes, but I do not know whether any were actually ordered.
The old BMT standard steels ended up in several configurations. A cars were single cars, doubloe-ended. B cars were triplexes with a cneter blind motor and a motor with one cab at each end. BX’s had a trailer in the center instead of a blind motor. BT’s were just two cars, basically BX’s with the trailer removed. Of course all could multiple together. Trains were limited to only one trailer in a seven-car train, Trailers were also prohibited on trains using the Manhattan bridge because of the grades.
The IRT had both motors and trailers, and until the 1939 Worlds Fair cars came, all motors were double-ended. The limit was three trailers in a ten car train, two in a five-car train, and one in a three-car train. Except that Flushing and Astoria trains had no trailers because of the grades to and from the Steinway (42nd Street-East River) tunnel. These cars were also called Steinways, because they had a lower-speed gear ratio, made up by field shunting, thus a more powerful car for the grades. The 1939 cars which were styled more like the IND R’s than traditional “Low-V’s,” but could mu with them and had identacle electrics and mechanicals, but single-ended with one cab in each car, usually run back-to-back with many assuming they were married pairs. But when Flushing-Astoria steel IRT cars could no longer access Lenox IRT Shop, the shop moves to Coney Island over BMT tracks from Queens

But they were separate cars, and I understand there was or is a photo showing one at the head of a train with the rest all regu
The MTH HO R17 look great but there’s allot of improvements. First of all the top round red and green lights are omitted “not lighted” All the lights in the trailer cars are omitted. The train is setup like a traditional locomotive hauled train because a large engine occupies the first car instead of powered trucks or underbelly drives. Last but not least the cars are blatently spaced too far apart. At least there are seats and poles in the interior.
Seems like the compromises a manufacturer of toy trains would make. But I suppose nothing more like the prototype is available?
Or could one buy these and work them over with powered trucks from someone else, do the interior detailing (not too hard with only side plastic hard seating) and modify the coupling arrangement?
What color schemes are available? In their lifetimes, the R17 were deep almost black green, grey and blue, deep Burgendy red, and flaming red-bird red.
The undercarriage of the MTH R17 is a metal chasis, so I will replace it with a plastic one from another vendor. You can use NWSL powered trucks under a plastic undecarriage which looks more detailed and realistic than metal ones.
