Dear Bachmann: I am the proud owner of a pair of GE 70 Tonners I am just delighted with them. I did notice that the coupler shank which came with these engines was way too long for realistic appearance. I installed the shortest shank couplers I had in my spare parts box. The locomotive footboards are now a realistic distance from each other yet still navigate the tightest industrial spur on the club layout with out touching each other. Two minor weaknesses have made themselves apparent. (1) The headlights at one end of the engine could be a little bit brighter. Is there an easy fix? (2) I admit that they are a bit noisy however and wonder what can I do to quiet down some of the noise I hear? If sucessful in this endeavor; I would then like to add sound to these very good running models. Do you have plans to produce a decoder to fit this engine with sound capabilities built in to it? (FYI) I ran these two locos today on a 15 car plus caboose coal drag on the club layout. I purposely chose to run the train against the steepest grade on the mainline. The train never stopped moving in this stretch but did slowly but steadily climb the hill between Galt and Newton. These tracks are located in a cut so I was not able to observe whether or not wheel slip existed. All in all; a really nice product but it does need sound. Yours, William Rupert
