Hi All, does anyone know if there is a standard length for the the two sleepers that have the point lever attached (early 80's BR)? Cheers Richard |

No specific information about the length of the timbers, but I guess that would make them about 13ft. regards, Martin. |

Thanks for that Martin. Another little question...... When nudging sleepers, is there a maximum distance apart they should be - the particular quandry I have is the point at which the point sleepers give way to the standard track sleepes - I seem to end up with horrible looking "trianges" sometimes. Cheers Richard |

Chairs are generally on the centre of the timbers, so that is the maximum timber spacing too. Where there is a rail joint, the chairs each side should not be more than 25" centres. On modern track with concrete bearers the bearer spacings are getting closer with increased loads and speeds. - the particular quandary I have is the point at which the point sleepers give way to the standard track sleepers - I seem to end up with horrible looking "triangles" sometimes.There are no hard and fast rules and it varies between companies. The GWR and BR(W) used a great swathe of long timbers under V-crossings and crossovers. On the LNER you are lucky to get two or three long timbers under a crossover. Generally as you move from round behind the gasworks towards the main running lines, so the timbering gets heavier and the number of long timbers increases. The "horrible looking triangles" do become much less noticeable when the track is painted and ballasted. But generally if you have a wide gap it's better to widen it a bit more and make room to drop in an additional bonus timber, possibly on a skew. But try not to have timbers close side by side, the maintenance gang wouldn't be able to dig under them to pack them level. p.s. "point sleepers" are usually called "crossing timbers".  regards, Martin. |
