As I've come to expect from BLI, an excellent loco. (Mine is the Pennsy version, though they make it in Penn Central, Amtrak and others) Good weight and traction - strong motor - excellent pulling power Sound is very nice, accurate rendition of a GG1 (to the best of my recollection - it's been a LOOONG time). Horn is great. Detail and accuracy is very good. I actually thought they had one thing wrong (door-window) until I happened to be in Harrisburg and ran by the station to see the 'real deal' on display there. I was wrong, they were right... General running characteristics excellent - smooth, quiet. And with street price down about $135, an excellent buy I think - I got mine for $127 on Ebay when they were streeting for $175+, but prices seem to have come down of late. I'm a 'steam baby' and only own a very few non-steam locos due to the era I model... This one is a happy addition and a likely candidate for adding 1-2 more to the roster.
