M-7, three duplicates and a two pair of spare trucks reportdly came to the railroad November 5, 1993 from Kovanchick Salvage's acquisition at an Algoma Steel plant in Sault Sainte Marie. They are double ended diesel-electric locomotives with two engines. They have two 150 hp engines, one under each hood, and one traction motor in each truck directly powering one axle which is chain coupled to the other. The engines are variously said to be 671 Detroits and Allison 4 cylinders. They differ mainly from other GE 44-toners in their undercarrige, which is divoid of tanks and resrviors and instead has a pair of variable gauge trucks. What would later become M-7 and a sister were displayed at the 1994 Fall Spectacular, but did not enter service until a problem with #15 at the June 1996 opening. 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 locomotive. They also did mechanical work on it as well and maintain the loco. M-7 pulls excursions when a steamer fails and another cannot be hostled in time. She also does switching. She wears a smart medium green and red scheme with black trucks and yellow accents. The origination of the scheme is a bit of a mystery since it doesn't really match anything else the EBT has.

It has been ascerted that M-7 is a 50 tonner. The variable gauge trucks are quite a bit heavier than the fixed standard gauge trucks on a standard 44 toner, though the carbody seems to be a bit smaller. The true weight of the unit is uncertain, though it is in the 44 Ton class. It's actual weight is likely 47 tons.

M-7 has been observed hauling as many as six fully loaded passenger cars.
