I would like to suggest that f we ever get the southern part of the WCML that the castle at Berkhamsted is modelled and included as a player explorable area. The castle is just across the road from the north entrance to Berkhamsted station and provides a good vantage point for seeing passing traffic on all four running lines, both from the embankment that is between the remains of the double moat and the top of the Motte (big mound where the castle keep used to be) in the far corner of the site. The castle has a bit of history with the railway. When the line was built, the remains of gate house were demolished to make space for the line and the rest of the castle protected by the Act of Parliament that allowed the building of the line.
