Talk:Harmelen train disaster
From Wikipedia, the free encyclopedia
While the ladder crosser at the junction increase the length of conflicting trackage by a small amount, it is really doesn't make much difference.
More important are:
- length of overlap from red signal to fouling point at junction.
- for moderate cost there could have been two warning signals approaching junction, say a double yellow and a yellow.
- in view of lack of ATP or ATB, there could have been two red signals protecting the junction, with a really long overlap from the first red to the fouling point.
- special rules when there is fog, although this is really only required with kerosine lit mechanical signals.
