Abstract: The hoisting mechanism known as the Engine Jack is an apparatus that may be positioned between the rails of a section of model train track such that it provides support for a model train engine while maintaining electrical contact with the rails. The Engine Jack enables model train engines to operate while standing still, yet providing the illusion that the model train engine is on the track. This allows the model train engine to be either serviced or put on display while the model train engine is running.
