Kato N-scale NW2 shell removal

Got this Kato NW2 i want to paint, any suggestions on getting the shell off and on. Does the shell come off in one peice like Atlas stuff or does the railing etc come off seperate its cool in the Atlas site they have this info , could not find it in the Kato site.

Thanks

The shell is one piece, you just need to do the usual wiggling back and forth and it will come off. Just be careful because there are no screws that hold the frame together so if you remove the fuel tank as well the frame will seperate.
