Ok I'll give you a little description about the system and how i want to run it, the system consist of R1 Larchmont line, R2 Hempstead/Fort mill ext(ft mill non electric), R3 Greenwich Line, R4 Norton line(shortest line), R5 Malvern/North wale ext non electric(main line), R6 Stamford line(longest line), R7 Newport line, R8 Hunton line. The fort Mill and the north wale lines are non electric meaning they run off of deisel motor and they run every hour or few hours similar to the LIRR's Greenport and Port Jefferson lines. the main terminal for all trains is central terminal where at certain times like roush hour you can catch every single rail line. the Riverfront Terminal(spin off of the Atlantic Terminal in Brooklyn, NY for the LIRR) is for every train that goes to the Freeport station(spin off from the LIRR's Jamaica station in queens) there you can catch the R2, R4, R5, R7, and R8 lines, but mainly the R2(electric), R5(electric) and sometimes R7 trains will be running from central but you can take them to Freeport and connect with the R2(Diesel), R4, R5(diesel), R7 and R8 lines at freeport. all other trains like the R1, R3 and R6 will always depart form Central. I want to run a scenario of this system that's why i need some assistance, if you live in NYC or Long Island and take the Long island Rail Road most of your life you'll understand how I want my system to run. I want to make two scenarios where you can play and the scenario starts at night and if you play long enough you'll wind up in the morning and one where you play in the day and if you play for hours you'll wind up in the night. you can ride the train and let it do the work or you can control it, the scenarios would only end if you brake a rule, derail or don't follow given directions. other than that they are everlasting scenarios and you will see service changes as time goes by. If you decide to leave a train for another one make sure that the train your controlling is stopped at a station why? so it can continue on its own like in real life as if a engineer decides to leave a train and another engineer is at that station and takes over, or else the scenario will end on you for letting a train run loose on a occupied rail line. and their will be times where your service is up and you have to take a train to a yard or portal and pick a different train to drive. Well this is how I plan on running my scenario now all I want to know is how can I make that happen with SCS2006 why? because I heard it was a good tool for running scenarios.
