This SimSig simulation covers a large geographical area between Dunblane and Ladybank to the South and Aberdeen and Dyce to the North.
The sim notionally represents the area around 2009 and is controlled from 25 mainly small mechanical boxes. Features include mechanical interlocking and Block Bells.
This Sim is probably of a medium difficulty rating for a solo player. The Block Bells make it a "fun" option for multiplayer games.
The supplied 2006 timetable has 281 trains and a later start 04.45 timetable with 257 trains
