It is the one listed in the current online catalog, a spectrum, DCC ready, 12 wheel drive,  in the green box. It was purchased from an online retailer since there is no hobby shop within 50 miles. I am hesitant to try and disassemble it since it is super detailed and I don't want to risk damage to anything.

Just got a GE E33 locomotive (product # 82403) When I did a test run I noticed right away that it has lots of vibration, I could feel it through the table and it is excessively loud. I have a Bachmann FTA and GP50 that both run smooth and quiet. Anyone else have an E33 that runs like this? I haven't yet looked at the drive train to see if there is a reason for this. ...Looks like this one may have to be a warranty return.

I recently purchased an EMD GP50 (#61292) with the new knuckle couplers. The couplers sag and won't stay coupled to anything. I attempted to replace the original couplers with with the correct Micro Trains replacement but after four hours of total frustration I have given up on that fix. I only discovered that I am not qualified to be a micro surgeon. Anyone else have this problem with these new couplers? Does Bachmann have a fix for this?
