Can any locomotive be converted?
It hasn’t been done in Z gauge yet, but apart from that, pretty well any locomotive can be converted, although very small locomotives are more difficult. The smallest locomotive known to be converted is a Lima Class 08 shunter, but for such a small locomotive, a new motor and chassis was essential. In O gauge, anything can be converted, but very small locomotives may require quite extensive rebuilding, so coupling a van holding the radio gear can make life easier.
