" said:My point is that if the interlocking size was smaller, such errors would be more immediately obvious in testing. I concede that boundaries are probably the hardest bits to test, though, and so simpler and fewer ones are better!Unfortunately not - smaller means more boundaries to test, and they are far more difficult to test than a regular route or auto section. Currently Milton Keynes is broadly split into three interlockings - the immediate station area, one to the north, and one to the south. Every route in to, or out of, the station crosses an interlocking boundary. If you make the interlockings smaller then you have to introduce a new boundary - probably split the station into slow side and fast side. Another boundary expands the data and testing greatly, especially as you somehow have to figure a way of not allowing any route to be part of more than two interlockings - which can result in some funky boundaries - or limit the track layout to prevent a route crossing two different boundaries. Had this trio been a Westlock capable of running it then the boundaries with the adjacent interlockings would have been plain line to the north and maybe 4-5 routes to the south. Instead there are - very roughly - around 100 cross boundary routes. Then there are the axle counters that inflate the logic but let's not go there. :whistle: SimSig Boss Last edited: 08/01/2015 at 06:50 by GeoffM Log in to reply |
