I am puzzled by Templot timber numbering of slide chairs as it appears to always show one extra slide chair. For example for a B switch the timbers are numbered from S1 to S11 but British Railway track lists 6 P chairs and 4 PL block chairs. In a diagram it also clearly shows that 11th timber having two L1 half chairs. What have I missed? Geoff |

Hi Geoff, The numbering is simply a reference identifier for the cut timbers during construction, and for the shove timbers function. It is not related to the chairing. The "S" stands for "switch" rather than "slide". Templot doesn't (yet) show any chairing information. For that I recommend referring to the P4 Track Co templates from Exactoscale (see: Exactoscale P4 kit ), which are available for downloading on the Exactoscale web site: Exactoscale P4 B8 template Here for example is part of one, coloured in: chairing_patterns.gif They are excellent detailed drawings -- zoom in to 400% or more to see the full detail, as above. But remember that exact details vary by prototype and period. See also: topic 780 - message 4620 regards, Martin. |
