Turntable speed?

[Bill H.]

A "new & improved" engine facility in on the things to do list. My current table turns at 1 RPM. I've always thought this was somewhat slow.

Any ideas as to what a realistic speed is?

Thnx...

Is it the type people used to push, or did the prototype have a motor? the hand powered ones, where as fast and you could push.....The motorised where still slow. I don't have the exact speed, sorry

One rpm is right in the middle of center field for powered turntables, and probably a bit fast for the 'armstrong' variety. Part of the reason was that the propulsive force wasn't high - 25 or so horsepower for electric drive, a half-dozen or so manpower for manual. Another part is that it was wise to be gentle when moving large containers full of loose water - embarrassing things could happen if it started to slosh around.

One problem with realistic speed here is the effect on fast-clock operations, where that one minute becomes five, or six, or ten - with timetable schedules demanding locos that have to be turned.

yes, never thought about the fast clock issue, very true. opps, another job for the crane.....

In the depot where I work, there is a powered 75-foot turntable which is still in daily use. It takes just under 60 seconds for it to make one complete revolution, so I'd say 1 rpm for a model is just right.

Cheers,

Mark.

One of the other members told me about the following motor.

It operates at 6 RPm and can also crawl. It works my TT without flaw or hesitation!
