Transport Fever 2: Special Service

This is my Xmas present to anyone interested in the Metropolitan Line. It's a realistic recreation, made on a 1:1 scale with Transport Fever 2; but this is not a normal service and it's not with a normal train. We travel from Chesham to Watford via the rarely-used North Curve and our transport is the venerable A-stock.
There are many excellent cab-view videos of the real thing and other games have done it, notably Train Simulator. This layout has been made just for fun and to see how far TF2 (and nearly 200 mods) can be pushed.

Important - Limitations of this medium

I can only use the assets (houses, stations, rails, scenery etc.) available either in the base game or generously made available by modders. The London Underground uses fourth rail electrification, with two driving tracks and two electric. The closest I can get is by using a third rail mod. Equally there is poor support in the game for stations with entrances above or below the platforms, but this is the way most real-life suburban stations are built. There is only limited support for LU signage
To build the suburbs of the UK needs a huge amount of varied housing, shops, offices and public buildings. We have some in the game but nowhere near enough. Putting them in one a time is tedious but there is no alternative. So I have concentrated on the streets around the stations and tracks, and left open spaces elsewhere.
Some assets, like fences and doors, flicker. This may caused by problems with TF2 or perhaps my video card is not up to the job. Sorry.
