These are 45 ton GE units. They arrived November 5, 1993. They were placed in storage in the EBT Locomotive Shop. They came from the Algoma Steel plant in Sault Ste. Marie as part of a purchase by Kovalchick Salvage.
They are 45 ton class in that they have a single traction motor per truck and the second axle is tied in by a chain and sprocket inside the truck. They probably weigh more like 47-48 tons. The trucks are plate steel rather than traditional and are designed to accomodate different gauge wheel sets. It will not go up to standard gauge but could to 42" or 30" I expect. They are double ended diesel-electric locomotives with two engines. They have two 150 hp engine and I beleive they are Detroit Diesel powered. At the steel plant they were set up as remote control units (not the same as MUing, but a start I suppose.)
The units were displayed at the 1994 Fall Spectacular, but did not enter service until a problem with #15 at the June 1996 opening. The unit that would become M-7 pulled the train. At the 1996 Fall Spectacular she was officially dubbed M-7 with her new paint scheme. Railways to Yesteday volunteers repaired the bodywork and painted the loco. They also did mechanical work on it as well. M-7 pulls excursions when a steamer is out of service. She also does switching. The units were not equipped with train air brakes, but brakes were fitted onto M-7 for use at the EBT.
Of the other three units, two were considered restorable to service and would crank at the time they arrived. EBT/Kovalchick still has two pair of spare trucks for these units I'm sure they'e be willing to sell to D&S for the right price. (Please, they are in the way!)
Below is a photo of M-7 before the addition of handrails on the side. If anyone really wants photos of the other units I can scan them in.
