The first type of dead rail are large plastic trains designed as dead rails.
The next two classes consist of regular trains that have been converted to dead rail. Some are home-made, while others are, ahem, home-made by people who sell them to others.
The second group actually does consist of reputable dealers, but when you check their sites, you cannot find a list of items and their prices. I can find NO major company except Lionel that makes dead rails, and Lionel only makes the first type.
Most of these locomotives are G scale--the large size makes conversion easier. There's a few O gauge out there. And home manufacturers have made batteries small enough for HO dead rails, but they are scarce.
However, they can run on regular tracks and can pull regular rolling stock.
