For my next “Market Garden” battle I have a large rail bridge for which I already have one straight rail hexagon tile embanked to the correct height.
My problem is that I also have two road/rail crossing points to create. I already have these crossings at normal ground level.
Option 1. I make sloping railway hexagons to drop a height of 12mm over 10cm, which is a far steeper gradient than would look realistic.
Option 2. I keep the railway embanked at 12mm height and create bridges (real or indicated by painting) beneath for the roads. To do this I might need to carve beneath the normal terrain level to make a useable bridge.
The photo shows a Sherman tank (based) with the current embankment and a normal ground level railway, and an indication of the slope required for option 1.
Nominal ground scale is 1:2500, but vertical scale is 1:285.
I think that by setting up a mock-up and having seen the result I use the exaggerated slope method. So now all I need to do is to make two convincing sloped embankments and fit (and paint) the rail tracks..
The number of bespoke Kallistra hexagons in my collection is getting a little worrying, but it is keeping two companies in business – Kallistra and Really Useful Boxes!
