I will give an explanations in brackets (...) and critical notes in red
File menu:
Open track database
Save processed track database (will be opened much quicker next time) not map itself
Index TSECTION.DAT (accelerates further map drawing) not *.tdb
View menu:
All looks correct
Side panel:
Map items
Gradient (=slope?)
Restricted speed zones (speedposts)
Pointers (=leading lines?)
Used tiles
Joint points of track sections not paths
Scale ruler
Sidings (парковые пути=YARD TRACKS literary)
Milepost's Figures size factor
Gradient figures size factor
Thank for this work. Looks cool!
