The is the base session for the Midwest Central route, Release 2 BETA3 <kuid:87783:1198:3> 28 December 2007.
This session contains no rolling stock, but is designed as a template for those who wish to create their own sessions based on the Midwest Central route. MidCen makes extensive use of the Invisible Speed Signal to control train speed through turnouts. The ISS is, however, a session-based control, so if you load the map without a session, all of the ISS controls revert to their default (off) settings. There are more than 70 of them in the map and programming them yourself will be a very time consuming process. (Not recommended)
To use the base session, load it along with the Release 2 map into Suveyor, then immediately save the session under a different name of your choosing. Then add any rolling stock you wish to complete your new session. If you create one you like, I invite you to submit it for consideration. Accepted sessions will become a part of the MidCen world, will be posted on the DS and the author will be given credit. Please see the Midwest Central website for details.
The site also has an operations manual and a printable system map, both of which have been updated for Release 2. http://trains.0catch.com
