The rails themselves are metal. The 'sleepers' the rails rest on are often made from wood - as they flexes while the trains pass over them.
Spare wooden track can be purchased from toy shops that sell the wooden Thomas sets like The Entertainer and Argos. However cheaper wooden track is available from Tesco and IKEA that will fit most of the wooden Thomas trains, and link up with existing track.
Yes, however, die-cast trains will not fit on wooden tracks.
The metal that trains travel on is called railway or railroad track. It consists of two parallel steel rails laid on wooden or concrete ties, providing a surface for trains to travel on.
Wooden trains can be purchased from a variety of stores both online and from local stores. Toy stores such as Toys 'r' Us would sell wooden trains. If there are none locally, their website would be an option.
While Amazon and Toys R Us would probably have wooden trains, I would recommend www.woodentrain.com/ which has hand-whittled wooden trains for sale. These may be more pricey than the alternatives, however.

The wooden plank laid down on a railway track is called a "railroad tie" or "sleepers." These supports hold the rails in place and help distribute the weight of the trains. Traditionally made of wood, they can also be constructed from concrete or steel in modern railway systems.
