The Progressive Rail Set is a NewGRF that serves to make upgrading of larger, advanced rail systems easier. Assuming a progression of Normal Rail -> Electric Rail -> Monorail -> Maglev -> Vacuum Tube, an engine can now run (unpowered) on the generation of rail before it and run powered on its "normal rail" and the next generation of rail.
The Progressive Rail Set requires OpenTTD, which is a free download from http://www.openttd.org/. The Set has been tested on OpenTTD 1.2.3, but will likely work on earlier versions.
If you want to use Vacuum Tube tracks, you'll use a separate NewGRF to provide them.
The easiest (and recommended) way to install the Set is use OpenTTD's
Online Content interface. Search for
Progressive Rail Set. This also
makes it very easy for me to provide updates.
Manual installation can be accomplished by putting the
file you downloaded in the
Once installed, the Set can be selected through
NewGRF Settings on OpenTTD's
There are no settings for the Set.
At this time, I think the Set is feature complete, so I am not adding any additional features.
To compile it yourself, you'll need NML. Then run from the command line (after fixing the paths as needed):
nmlc progressive_rails.nml --grf=progressive_rails.grf
If the Set brakes or doesn't work the way you'd expect, please report the bug to: https://github.com/MinchinWeb/openttd-progressive-rail/issues
