If by 'train' you mean a railway locomotive, then the answer is 'locomotive' e.g. At the turn of the 20th century the transport infrastructure was centred around the locomotive industry. If by 'train' you mean the verb to practise then I can't help you.
A locomotive is what supplies the power. A locomotive can in itself be considered a train depending on its function. A cowcatcher!
