I'm from Fort Worth, and you can easily kill a few hours all within walking distance of the train station. But yes, the free downtown bus does stop there. The station is on the east side of downtown and you can walk to the Fort Worth Water Gardens, Sundance Square, Bass Hall, Rail Market and any number of very good restaurants.  I believe you will find downtown maps at the station. There is also another train station nearby on the south side of downtown - the Fort Worth Texas & Pacific (T&P) Station that you might like to see.  Both the T&P and the Fort Worth Intermodal Transportation Center (where you will arrive) are stops for the Trinity Railway Express which is a commuter train between Fort Worth and Dallas.  A few miles north (not walking distance) is the Fort Worth Stock Yards which is one of the most popular tourist attractions in Texas.  The stockyards is a stop for the Grapevine Vintage Railroad and includes a working turntable.  Plenty more to do in Fort Worth, but with only a few hours to kill, this is already more than you'll be able to take in.  Hope this helps. Have a good trip!

There is a file called UTC_Manual.pdf on the disk for TRAINZ Ultimate Collection.  I haven't gone through it so I don't know how much detail there is or how much help it will be.  Should be a good place to start though.

If you have a Half Price Books store near you check there for TRAINZ titles.  I found "TRAINZ The Complete Collection" for $4.95 new.  It includes:

The store near me has several copies and I've seen it at other HPB locations as  well.
