What is the PATH and HBLR system. For PATH are you referring to PATH as in the Port Authority Trans Hudson which is a subway communter rail network that goes from The New York City Borough Of Manhattan to New Jersey? If so I would love to see PATH as a use it often actually
Hblr stands for Hudson Bergen Light Rail NJ Transit. That one is easier to do because Dovetail games has a license to use NJ Transit. Just look at train Sim 21 NJCL, Morristown Lines
The Hudson Bergan Light Rail system is a good suggestion if they decided to make a Light Rail route for TSW 2
