I wonder if anyone knows how long the sleepers S1/S2 are extended to support the point machine? I realise this might be a "how long is a piece of string", but I'm concerned with the typical point machine seen along the older bits of the WCML (i.e. not switch point clamps). Looking at http://seva.eng.ox.ac.uk/research_railway_points_machine.html those manufactured by Westinghouse Signals. My usual sources for this information cop out by stating "these timbers extended to suit signalling engineers needs". Richard. PS: Sorry if I've got the terms completely wrong - it's been a long month  |

Oops - google is my friend, this is quite interesting... http://www.westinghouserail.co.uk/Repo/datasheets/SURELOCKL3.pdf Seems they are 430mm wide, but there is a gap between them and the running rails - wonder how wide that is? Richard. |
