Hi Gordon. Not to get confused Iam Phil Houghton. Better late than never.. I have just finished reading all your 69 threads. Just to say you are a Master Craft's man in respect to your
layout work as to track work and all the rest. Is templot what you get when you do your own track work, or is it a computer aided track system you work from. I only no of winrail . com
and anyrail.com as track planning systems. Hope you do not mind if I take you back to thread 42 ie/ Gradients you may now have completed this work. I have always used the calculation
as to overall length including transition at both ends Divide in to the height that is required, if you only have 13ft = 3,939mm divide that in to 70mm = 0.0177 % before your point work.
On working with my son on my grandson layout we have 4 tracks coming down over 8mtr to go under terminus with 100mm height = 8000mm divide into 100mm= 0.0125 % we have on
trial no problem with di-cast wren loco's pulling 8 coaches gets harder over 1%. for every 96" you drop 1" so that's 8ft drop per1" to maintain the 1% requirement. That is why I think you
may have to move your point work back to wards your junction. I look forward to your layout being completed and more threads.
PS Hope you & wife are in good health. Regards Phil Houghton.
