Bogie and pony wheel swing calculator

Postby Julian Roberts » Tue Apr 10, 2018 10:14 am

Here is a spreadsheet calculator for working these out. I don't know if something like this is already available here somewhere. If it is and it's better please say so someone and I'll erase this.

As I know nothing about maths, computers, etc, I can't help if anyone has any questions. My son put it together for me; he has the grey matter I lack. Hopefully it still works from being downloaded to my phone and uploaded here.

I find it useful to know in advance for example whether drain cocks are going to be clouted by a pony wheel on a 4ft curve, and how much they need to move out if so.

Although he has labelled it a sideplay calculator this has nothing to do with sideplay of the wheels within the rails. Sideplay will vary according to the Back to Back and any gauge widening; this spreadsheet makes no allowance for those things.
