Stuntmanmike,
Welcome to the forum!

Your father left you  some nice Post War trains & accessories,
Mainly Lionel, but I do see a nice tinplate Marx Glendale station
and  windup train track switches.

The following links will help you identify the individual pieces and
give you some idea of value.  You might also check the completed
auction prices on the online auction sites.
