Bazoooooom, there goes your train right by the signal and into an accident.........[/quote] <br /> <br /> <br />I've got myself thinking again. First the scenario: <br /> <br />We got a crew running a train down some very 'foreign' track....they are out of their normal territory for whatever reason. They've 'downloaded' the books, schedules, tables, etc, and for the most part things make sense, but once in a while they get kinda confused. <br /> <br />Anyway they are approaching a junction which has a three signal heads. However the top head is burnt out, so instead of seeing three heads, they see two. This junction has not background lighting, the area is fairly wooded with trees and bursh, and maybe in terms of documentation it is also simplied. Another train is approaching the junction, or perhaps has just left and stopped. The first train, will be using the same 'exit' route as the 2nd. Would the crew not seeing two lit heads instead of the three give them incorrect information.....and thus lead them into disaster? Instead of seeing R/G/G (Rule 418 - Proceed, medium speed passing signal and through turnouts, approaching next signal at medium speed) they instead see G/G (Rule 405 - Proceed). <br /> <br />What prevents scenarios like this??? I know this scenario may not be technically possible, but I think ye all see my point.......just trying to learn here.
