Now here's a trackwork challenge

As blog readers will know I like track - narrow gauge, broad gauge, chaired, flat bottom and even trams. Thus I was in seventh heaven with a holiday in Lisbon over Easter where the narrow gauge tram system with both old and new styles of trams exhibit every classic type of track formation and runs up and down unbelievable gradients - one tram had to apply it's skid brakes before descending a hill.

I modelled trams in my youth and could be tempted again one day to try and replicate the type of scenes below.
