Does anybody know of anywhere I can find any information on shoving timbers? In particular I have a turnout adjacent to a single slip as in the screen shot and I'm not sure what to do. Should I move the timbers (though I know key timbers cannot be moved) or should I shorten the timbers on the slip and the turnout. Btw, these are FB turnouts circa 1983. Cheers, Adriano 162_010803_080000000.png  |

Btw, these are FB turnouts circa 1983.Adriano, You might consider combining the timbering of the turnout and the slip to make long timbering under both formations. The timbers around the tiebars on the slip and the turnout are almost in alignment and should combine into long timbers which could be angled to provide sufficient room for tiebars and correct placement of slide chairs. You might also consider extending the long timbering to the left through the crossing on the slip up to the long timber at the turnout to the left. To the right of the tiebars, you might manage to retain the individual timbering if you can interlace the timber ends, but you might have to resort to long timbers under both formations. You also have the option of using wider 14" timbers if you find that chair or baseplate placement is difficult on the standard 12" timbering. Have fun - timber shoving is the new rival to chess.  Jim. |

Hi All Is there a general rule about this? Some pointwork at New Street was interlaced while some (that for all intents and purposes was the same) had long timbers. Not that it matters too much as I will just copy my pictures but it has got my curiosity up! Cheers Jim |

Hi Adriano What you need to watch out for is the timber angles on the switches of the slip. The timbers have to be parallel with the tiebar - on your screenshot they're not. If you twist the slip timbers so they're parallel with the tiebar, I think the ends will interlace nicely with the switch on the turnout. You can't use blocked crossing work across the turnout and the slip because of the differing tiebar angles. Jim suggests using 14" timbers. I've done this on my example because it fits the period, but were 14" timbers used ca.1983? I got the impression they'd long disappeared by then. Below is a screenshot of a section of my current plan. Have a look at the timbering of the slip - this was more or less taken from a scan of an actual slip drawing. 105_140920_120000000.png  |
