Hello everyone. Great news. I finished my first semester of college, passed all tests, quizzes and subjects so far. I'll be getting my grades next week along with two more results from the finals. It feels great to have a 5 week break, after weeks of constant study for midterms and finals. For the next 5 weeks, I'll have some time to make some progress with the Major Tri State Area. I decided that I want to take a bit of a break from working on the upper Hudson line. I am going to make the effort to get some more work done on the SunnySide yard and trackage into Penn Station. Would anyone have any advice on catenary. I am not really sure how to work with the catenary. I know they are the overhead wires but I know in Trainz, there are things like transmission wires, crossover wires, and gantry bridges. I would also like to learn about the different signals, where they should be placed along the track and the rules for each signal. Hopefully, if I get a majority of Sunnyside done, I can begin to work on the MTA #7 subway line from Queenzboro Plaza to the Future Hudson yards #7 terminus on the West Side.
