I've just started work on a 4mm "OO" scale layout in order to take advantage of the recently released models of the LT Museums new "S-stock" as well as the Heljan Metropolitan Bo-Bo locos. |

4railsman wrote:Hi, Welcome to Templot Club.  Templot has no direct support for conductor rails. However, for plain track you can improvise by using the platforms function, adjusting the dimensions of the platforms to represent the conductor rails. The centre rail needs to be set a negative front dimension for the "platform". The position and length of each such "rail" can be adjusted: 2_271834_370000000.png  See: real > platforms... menu item. This does mean that you can't have platforms on the same template -- where needed they would need to be overlaid as a separate partial template. To represent conductor rails through pointwork it will also be necessary to overlay partial templates. regards, Martin. |

p.s. Everything you could need to know about 4th-rail track is on Russ Elliott's page here: http://homepage.ntlworld.com/russelliott/3rd-4th.html Martin. |

My only concern for the information being maintained on a "personal homepage" is that it could easily disappear if Russ Elliott changed his ISP and could then be lost for all time. Is there a way that this information could be safeguarded by being made available on the Templot or Templot Club websites ~ assuming of course that Russ Elliott is in agreement? Whilst there is a table on page 46 giving a list of crossing angles, it refers to the various "Switch Types" listing A through E but not providing illustrated details of what any of these switch types look like. So I am now struggling to locate any information details particularly relating to the Metropolitan Railway as well as later London Transport/London Underground specifications for turnouts and crossings ~ for example:- I don't know the preferred crossing angles; or the preferred switch blade lengths or even how the turnout was “timbered” – so any contributions on this subject or pointers to already published articles would be most welcome. |

Before I start work on building a new OO FS layout to feature the new Heljan Metropolitan Bo-Bo locos, I need specific information or a Manual covering the standard track, switch and crossings used by the Metropolitan Railway and the London Transport Executive/London Transport Board during the period up to 1970. Thanks to Martin Wynne for this link http://homepage.ntlworld.com/russelliott/3rd-4th.html which is most interesting and essential reading for anyone intending to model the current London Underground and its predecessors including the Metropolitan Railway. Whilst there is a table on page 46 of the link above, which gives a list of crossing angles, it also refers to the various "Switch Types" listing A through E but not providing illustrated details of what any of these switch types actually look like. Does anyone know of any published information (book or on-line) that provides data specifically relating to the Metropolitan Railway as well as later London Transport/London Underground specifications for turnouts and crossings ~ particularly the preferred crossing angles, switch blade lengths and timbering details used in the period up to 1970. |

These switches are the bog-standard REA semi-curved bullhead switches. They are created by default in Templot -- you can see the dimensions by going to real > switch settings... and clicking the show switch info button. For more info see also: http://templot.com/martweb/gs_realtrack.htm http://templot.com/martweb/templot_forum.htm and also on the Scalefour web site. For printed information you need BRT up to the 3rd edition (1964). See this recent topic: topic 2777 I would recommend that you become familiar with standard bullhead track before getting in to the details of 3rd and 4th rail. Sorry I don't know specific details of London Transport switches. You could contact the CLAG group via their web site: http://clag.org.uk they are modelling London Underground in P4. regards, Martin. |

Thanks Trevor. Rest assured the information in Russ's exceptional work is safe, backed up and ready to deploy should anything happen in the future. You started two similar topics, so I have merged them. p.s. It would be good to know your name. Any chance of signing your messages? regards, Martin. |

There is a further issue to take into consideration. Prototype sleepers are 8'6" in length, 34mm in 4 mm / ft scale. oo track by default uses 32mm in order to compensate for the under scale track gauge and keep things relatively in proportion. This means either the conductor rails will be too near the ends of the sleepers (if set at the correct spacings) or the sleepers need to be lengthened to 34mm, which will look rather odd. The choice is a personal one. Regards Tony W. |
