Thanks for all the input, its a good thing I asked first, pretty much we've been taking the junk trains we get in to keep the current fleet running and then if we get models we don't have ill try and fix them up if possible.
Yeah, the white footplate trains are all r/c which ill look into new remotes, one of the Percy's I think is a tna because he has alot more weights than any Percy I've ever seen and he has a funny looking switch on the bottom, but his tender is missing, Douglas is just a chassis and body no wheels or motor assembly (I cab get wheels and powertrain assembly from another train though).
The Thomas's with the bug eyes have are Tomy from 1992
R/C Thomas with white footplate is from 2006
R/c James with white footplate is from 2007
R/c Thomas flip face missing tender 2006
The narrow gauge trains are all Skarloey (the narrow gauge trains are my favorites!)
