" said:pheraps i write wrong. If i well comprise with TORR off i must delete the route after train passes it.Unfortunately, for some reason Westbury doesn't have a separate option to control it. If you want TORR on, you should run the sim in "Beginner" mode (you can still increase failures after the game has started). Log in to reply |

" said:Thanks for the explanation, I've always meant to ask how the interlockings actually work.Better late than never... geographic interlockings just form an electrical path from A to B - they find their own way. Yes, it'll find all the possible wiggles, and undesirable ones have to be bridged out. There's an inbound signal to the buffer stops of one of the platforms at Victoria (Central side) that has something like 9 possible ways to get there, but not all are available. SSI/Westlock/Smartlock, on the other hand, has no concept of automatic routing like that, though I believe tools exist to prepare data from some sort of CAD diagram, and then finished off by hand. They are basically just a specialised programming language, one written in a way that signal engineers can understand and use. The control system (or ARS) generate a panel request which is essentially a number (but identified by name), which goes into the interlocking's queue. When it gets around to processing it, it looks for a set of data identified by that name (number). That data is typically a set of commands, including if/then statements. Example: (Not all shown) Roughly translated: if R166B(M) available (not barred by the technician) and R166B(C) not set and subroutes not locked (free) and points controlled reverse or free to move reverse (crf) and points controlled normal or free to move normal (cnf) then set the route R166B(M) lock (l) the subroutes within the route control the points reverse (cr) or normal (cn) clear the button pulled state on the signal endif Westrace, as used a fair bit on the London Underground, uses a ladder logic which is basically "energise [virtual] relay X if <boolean conditions>". Microlok as used in the US and elsewhere is pretty much the same. SimSig Boss Log in to reply The following users said thank you: Hawk777, headshot119, Steamer |
