Picked up my pair of these little critters early last week,but waited till last night to check them out. First thing I noticed was all the fine detail including seperate coupler lift bars.The pair I bought are undecs so they came with all the details for both versions. Motor wise they have 3 pole motors instead of the more popular 5 pole unit.I couldn't see where it made any difference.They ran smooth and fairly quiet on our TTRAK layout for quite sometime. These are not the most powerful or strongest pulling locos I've owned,but they ain't the biggest either.It took both units to pull my 4 quad oretrain and they still had problems.Even with that,I'm still quite pleased with their overall performance as most of the time they will opnly be pulling 4 to 6 cars max and look good doing it. These little fellas will be serving a industrial park simular to the one owned by Progressive Rail which I believe is in Minnisota (SP). If anyone is interested I can post a scan and eventually photos of the completed units.
