1. Making Common Crossings - how should the tip appear?

... CLM and RAM diminishes.For modelling purposes the difference in angle is insignificant, but it makes a measurable difference to the lead length of a turnout. Try swapping from RAM to CLM in Templot to see the difference. So for 1:10 crossings (# 10 frogs): CLM= 2 x ARCTAN(1 /20)= 5deg 43min 29.32sec RAM= ARCTAN(1 /10)= 5deg 42min 38.14sec I shall leave you to dab your own calculator for the rest! Or you can use this trick in Templot: peg_ram_degrees.png Set a straight turnout, shift it onto the datum so that the rails are horizontal on the screen. Press CTRL-4 twice, and on the info panel read the angle in degrees for the peg. To find a different angle, press CTRL-0 (zero), change the crossing angle as required and repeat the process. regards, Martin. posted: 10 Mar 2008 23:37 from: Geoff Cook Brian Tulley wrote: Hi all, I spent yesterday trying my hand at forming a common crossing ...

2. Crossing angles

... right. Assistance will be appreciated. Regards Charles posted: 6 Apr 2018 16:42 from: Martin Wynne Charles Warr wrote: I need to know the crossing angle expressed in degrees and minutes. Hi Charles, ram_angle_diagram.png clm_angle_diagram.png Templot uses RAM by default. More explanation here: message 2081 To convert the unit angles to degrees, for unit angle N: RAM degrees= ARCTAN( 1/ N) CLM degrees= 2 x ARCTAN( 1/( 2 x N)) You can use this trick in Templot: peg_ram_degrees.png Set a straight turnout, shift it onto the datum so that the rails are horizontal on the screen. Press CTRL-4 twice, and on the info panel (scroll it down) read the angle in degrees for the peg. To find a different angle, press CTRL-0 (zero), change the crossing angle as required and repeat the process. For CLM equivalents, click real> V-crossing options> convert RAM to CLM menu item, and then do the above. e.g. 1: ...
