John, Great stuff!

FYI...The 24" ga. Plymouth 15-Ton ,model DDT, was built 1967 for Carpenter Steel, Reading, Pa.

The converted D/E Mancha probably operated at the same place.


Ray

no kidding. i was just at carpenter back in october. thanks ray!

john, next time youre out there hook up to that bw cable reel motor and drag it over here will ya?

Chris the problem with all the Baldwins there is that these should be all HIGH VOLTAGE 500 volts D.C. making this very unsafe & deadly if anyone comes in contact with the trolley wire.

To completely rewind a traction motor FYI runs between $10,000 to $20,000 EACH. (At least it is new then)

The 3-axle is a Baldwin main haulage locomotive.

The battery locomotives were the ones that everyone had seen at B & M Tunnel. The one with the axle equalizer bar over the wheels is the General Electric & the other is a Jeffrey.

Ray, which iron mine in New York did these operate at again.

Both came from a Republic Steel Mine iron ore mine in upstate New York.

Chris,

Is this the one that used to sit in a half-fallen down shack near Hazleton? I first saw that one in 1979. Pics somewhere...

hey rob, i heard of that engine but i never saw it. i would believe it is though.

if i remember right, the motors in the picture above have a draw bar pull (DBP) of 3000 pounds (from the builder's plate). i have seen general guidelines, based on the friction between the wheels and the rail, where the DBP is estimated to be one-fourth to one-fifth of the locomotive's weight on the driving wheels.

if 3000 pounds is right and we take the one-fourth figure, this should only be a 6-ton motor (7.5-ton using one-fifth), not the 20-ton figures i've heard.

(3000 x 4 =12000 lbs, 12000 / 2000 = 6 tons)

(3000 x 5 =15000 lbs, 15000 / 2000 = 7.5 tons)

what's the deal here? there always seems to be wide ranging estimates of locomotive weight.

would the serial number clear things up? i know someone has the serial number around here.......

or did it say 6000 pounds DBP?!.... then 13 tons would be about right.

no they were 3000 lb dbp. as for the s/n they were covered with that additional plate installed over the builders plate however we were able to make out the model number, now if adam would only post it up...........

I have specs somewhere on those I believe they were heavier than 6 tons. The way you calculated it John is correct but with the vertical brake wheel time period it was slightly different. 8-10 tons if my memory serves me correct.

considering mike's joy shaker seemed to be at least a ton

They should be 6-8 tons. Chris, if you have the model that will answer the question.
