I am trying to design a new layout based on modern practice & i would like to know what kind of sized pointwork would be used in a yard. What would be the minimum sized pointwork & what would be the maximum sized points used I.E B6 C10 etc etc. Hopefully once this is cleared up i can design the layout a bit better knowing that the pointwork is correct. Many thanks. |

Probably not much use but it may point you in the right direction. Cheers Phil |

What would be the minimum sized pointwork & what would be the maximum sized points used I.E B6 C10 etc etc. I visited the Birch Coppice railfreight terminal last week and as there is a public footpath right in front of the terminal and over some of the approach track I was able to take some pictures of the trackwork*. All of the S&C work was flatbottom rail on woodern timbers, but it's a fairly new terminal, and we think it's been relaid recently as the industrial units are popping up at a rate of knots and it looks different to some of the photographs we'd previously seen. I'll see if I can at least work out the switch sizes from my photographs tonight. Richard. * Just a quick note to say the terminal was shut for the night, with gates to the terminal firmly locked and the only locomotive present (56303) swithched off. The line has been closed (and is closed until Wednesday this week) due to landslips on the line to the terminal. |

I've attached a copy of the one of the switches I took a photograph of at the Birch Coppice Terminal. As they are quite new, as in within the last couple of years, I guess they are vertical switches, in which case they are B switches (or BV) - that is they have 12 slide chairs. If they were inclined switches 12 slide chairs would make them E switches - but I think that would be rather big for a freight terminal. I'm not sure how one goes about working out the crossing angle, if possible, using the types of chairs as a guide - I have other shots showing the angle if anyone can help. But as the shot is side on I doubt it would GIMP very well. What's interesting about this shot is the two sets of slide chairs at the end of switch tips. Note how there aren't centered in the timber but aligned with the edges of them. I knew the one over the soleplate is like that, but it's the first I've noticed that the next isn't centered as well. Interesting stuff - well I think. |
