Next on the list was locomotive power for the Maine Central local YQ-1, an out and back (returning as QY-2) from St. Johnsbury to Whitefield. Looking at the available units, I saw a few GP7s and GP38s. This job usually ran with one or two GP7s, but on occasion other power was used. I decided to MU GP38 258 and GP7 562. These are both Atlas units and have similar operating characteristics, They also both have Soundtraxx sound decoders making speed matching a little easier.

After speed matching was the important step of sound levels. First, these have different speakers, but more importantly I am finding the need to reduce volumes significantly overall now that most locomotives have sound. And in an op session environment, it would be ideal if only the general area occupied by the operator had that loco's sound, and could not be heard across the room.
