This unit is one of three M-7 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. This unit was stored for possible reactivation or parts supply for M-7, but was never used.

AS 4 s/n 32471 blt 8/55 This unit is currently (2006) being restored to service by the D&S.

It has been ascerted that these units are 50 tonners. 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.

The three unused units sat in the Locomotive Shop, except one that was displayed with what would be M-7 at the 1995 Spectacular. After the massive Colorado fires that cased great losses to the Durango and Silverton when their steamers had to stop running due to the fire thread, the D&S started buying some diesels at reserve power. After buying and restoring a nearly identical 47 ton Arkansas Lime unit, the D&S purchased these three spare units from the EBT and started the haul to Colorado Septermber 17, 2002.
