NYC Hudson loco 5200 line drawing

General Discussion
#1

Hi Guys:

Does anyone know of a link to view a line drawing of NYC Hudson 5200 J1a ?

This is the first Hudson for the NYC.

Thank you,

Norman

Norman, I have a line drawing of the New York Central class J-3A #5405 built in 1937, which, with the tender, was 95 ft. 11 in. long, and I have a line drawing of the Nickel Plate L-1B built in 1929 which is 85 ft. 6 in. long, and which is similar to the four L-1As built in 1927. Line drawings with lots of very specific dimensions.

(Neither drawing is the streamlined Hudson. I don’t know if your J-1A was streamlined, I guess not, but I have a line drawing for a Chicago and NW class E-4 streamlined version built in 1928 which is 101 ft. 9 1/2" long.)

Will any of these work?

They’re in my “World Railways 1950-1951” book, which was the first edition; the second edition came out in 1952-1953 but I don’t see what you’re looking for there.

However, this may end up being your best source:

Hi John:

Thank you for the link.

For this NYC 5200 J1a locomotive:

My main question is the detail part at the top of the boiler just behind the whistle.

What is this cluster of horizontal pipes?

On the NYC J3e there are three vertical pop valves located at this position on the boiler top.

Would you have a close up detail dwrg of this cluster of horizontal pipes for the 5200 J1a ?

Is a paper copy of this drawing available from a known source?

Thank you,

Norman

Hiya Norman, I don’t know the answer to those questions. You might be able to contact Carrdo at the Machinist Forum website and see if he can copy the drawings for you…otherwise, if the drawings I described from my books would help you I’d be happy to send them along.

An odd question about NYC’s Hudsons: Some had a small stack ahead of the stack. What was that for?

Hi Tom Ruby:

The J3 Hudson series ( and I guess some ealier verions ) had an additional steam piston mounted between the frames of the locomotive trailing truck under the cab.

The steam exhaust of this booster engine vented through the small stack ahead of the main stack.

This booster engine was used to start the train when pulling the long string of heavyweights. This booster cut off automatically at a set speed once the train was underway.

Neat eh?

Hmm. I knew about the booster cylinder, but didn’t know it was related to the little stack. I figured they’d have run it to the same blast pipe as the main cylinders.

Now I know.
