Are there any in Texas, how would I go about finding out?
Here's a link to the ASLRRA:

And to Texas specific shortlines:

There are 37 shortline railroads listed. You can click on each railroad's name for more information on each railroad. Some have another link to the corporate website, including route maps. Good luck!
