Here is the updated version v2.00 of Chiltern Railways. It incorporates several important changes to the route (for the purpose of realism and ease of operation) as well as corrections to some of the faults found in v1.00 Timetable.
All the changes are explained in the notes PDF included in the zip file attached. But FYI the key changes are:-
Removal of Marylebone TMD
Change in layout of Wembley LMD and its sidings for the purpose of realism.
Change in layout of Aylesbury, Aylesbury TMD and Aylesbury Vale Parkway for the purpose of realism.
Changes in platforming of some services at Marylebone to reduce the number of inbound trains that cross the path of outbound trains
Sig 59-13 introduced near Princes Risborough to act as a “holding point” for trains waiting on the single line from Aylesbury for faster trains on the Up Main to pass
I have not included a session file. Instead I prefer the use of the Preset Automatic Signal Routes button once the railway and timetable are loaded. Instructions are in the notes file within the attached ZIP file.
