My friend has the above locomotive. It has a QSI board in it and it is brass, both the tender and the engine. There is a 4 pin connector to the engine from the tender but it is separate wires and not bundled like I am use to seeing on MTH. It has the 16 wheel tender and the speaker is mounted on a cross bar in the tender body, and not mounted to the tender floor which is what I am used to seeing on MTH. There is a large Pittman motor in the engine. Is this an early MTH product? Or some other manufacturer? He is interested in me doing the upgrade to PS2 and it definitely looks doable but I am concerned about doing it if it is not an MTH engine. I could not find any MTH markings on it at all. It also has a 9 volt battery in the tender. The cab number is #6465. If anyone has info on this engine I would appreciate it, especially if you have upgraded it to PS2. Thanks.
I could not find it on the MTH website.
