ExactRail scale calculator

[Johnny B. Good]

Hello all,

Rummaging around the internet I found this - apologies if it’s already been posted somewhere else.
I was thinking about scratch building a Sentinel shunter, (in part because it’s mostly a box shape, and I found a diagram of it). Well this site allows you (for scratch building anything really), to take the measurements of say a real locomotive, choose the scale you’d like to build it in, and put in the measurements and it will instantly give you the converted measurement (in inches or metrics whichever you’d like). You could use it for “trains, planes and automobiles” (and buildings). I hope you find it helpful.
