The American city of Detroit, Michigan and the Canadian city of Windsor, Ontario form the core of this map. You'll notice that most (if not all) of the routes here, in this 1:1 scale recreation of actual Michigan and Ontario roads and cities using real world coordinates, serve their own purpose, including (but not limited to) connecting a suburban town to the main city, or transporting the locals around their town, all while using timetables lifted directly from real life.

The roots of this present map were first planted in late 2018 when I pulled my old and infamously destructive Detroit map from the internet and began contemplating remaking the map from scratch. In 2019, work on this map began, and after many weeks and months of hard work, the all-new, improved and more realistic Detroit-Windsor map is now available. The main intent of this map is to make it as large as OMSI will handle it, as an experiment.

You will already notice that everything is much more polished compared to my old Detroit map. Roads are much more realistic and detailed, and more realistic buildings are featured too.

The following routes are currently featured in the latest release:

• DDOT 19 (Outer Drive-Rosa Parks Transit Center)
• SMART 125 (Detroit Metro Airport [McNamara/Evans Terminals]-River Rouge)
• SMART 830 (Trenton-Downtown Detroit)
• Transit Windsor/The Linq Tunnel Bus (Windsor-Detroit)

Urgent Note: You must replace ALL repaints, HOF files, and the like when updating this map from previous versions, and select "load map without buses" when running this map for the first time. Failure to do so will create incompatibilities and cause glitches, for which no support will be provided.

Important Note: When spawning a new bus, each agency uses different HOF files. Use the following HOF files:

• route starts with "DDOT" followed by route number: use the HOF file "Detroit - Jun 25.hof"
• route starts with "SMART" followed by route number: use the HOF file "Detroit SMART - Jun 25.hof", "Detroit SMART - Sep 25.hof" or "Detroit SMART - Nov 25.hof" depending on time of year
• route starts with "Windsor" followed by route number: use the HOF file "Windsor - Jul 25.hof"
