Forum:Is it possible to create a rail that makes power by going over a rail?

I'm beginning to start using railcraft, and wanted to know if it's possible to make a rail with and MFE cart, if you can make a track that send the cart over to it, then the cart goes over the special track, that creates power. Not by a energy unloader, but by just making raw power right there, then sending it into the cart for lator use.

Anyone help? :#
