No I didn't notice any obvious crabbing but only had 11 wagons behind it mix of Bachmann, brass kits and white metal kits but the tender did rock from side to side a little but has full tender of real coal witch has eased that. When I opened the box the middle wheels was loose but quickly pushed back in and they are solid discs. All in all I'm pleased with it and have the Bachmann version on order and tempted by "green arrow" too but can I justify 3 v2s.
