I am currently building a new layout which will follow GW practice. The layout is in 4mm/EM gauge, using Templot & 'C&L' products. At one location I need a catch point to protect the 'main' against vehicles breaking away, and a trap point on a private siding to protect the main line. My questions are:- a. Which is the moving section of rail (ie which side acts as the switch-blade (I am assuming there will only be one rail which has to be actuated) and b. Over how many slide chairs would it operate? I've looked at various photos, but cannot really see the answer (pointers to more images welcome!). Kindest regards Ian |

The above book has a whole chapter on them, and several pages of drawings. By the way, to p.w. staff they were always "catch points" as the physical object, even when installed to provide the signalling function of "trap points". See: message 2357 regards, Martin. |

Hi All, First apologies to Scanman, as this is of no real help to him. Just read your comment regarding “Catch & trap - the GWR way!” by Scanman. I was intrigued by the book that was quoted on GWR track “Switch and Crossing Practice”. My question, is there similar books or documents for the LMS ? And are there any other books of this type for the LMS, relating to all aspects of their track work ? Very best regards. Brian Nicholls. |

Martin, Brian - many thanks for the replies... Puts me in a bit of a quandary - I've just filled out the membership form for the GWSG! Brian - I hope the answer is 'Yes'! Regs Ian |

Two books I would not be without - and they deal with trackwork in some detail, despite their titles, are: Railway Signal Engineering. Written by L. P. Lewis in 1932 and Mechanical Railway Signalling. Written by H. Raynar Wilson in the 30's. Now I only have part 2 of the latter and would dearly like to get my hands on part 1. Can anyone help? What I have are reprints, so they should be around somewhere. Regards Brian Lewis Brian Nicholls wrote:

Bless you Dennis. But I have one seemingly insuperable problem. I buy a fair amount on line, but as soon as I find I am on a site that insists on you setting up accounts/registering/passwords, etc. I go elsewhere. Sadly this is the case with Abe books. I do not know why businesses do this, it really is time someone told them they are losings 25-35% of their sales by adopting this stance. Folk generally do not like registering. I did try to see if I could find this bookshop elsewhere, but they do not appear to have a web site and are not listed in the telephone directory. Thanks anyway Brian Lewis Dennis Mowatt wrote:
