This railway was originally designed by J K Wok and extended by TUT several years ago but without a timetable. A timetable has now been provided.
The zip file includes graphic Central_Line_roundel.png. Please transfer this to your ‘Graphics’ folder, and note that program versions prior to v2.4.0 will not work with this railway because they weren’t able to accept user graphics.
