## About The Pull Request
Minor fixes to the tram crossing signal logic.
Reverts an earlier change I made to the subsystem, which resulted in the
signals being wildly off in their timings on a regular basis. Adjusted
the red length corresponding to the properly timed signals. Removed
define for degraded yellow, as that's now simplified into a check at
signal activation time.
## Why It's Good For The Game
Tram crossing lights better reflect tram status, staying green when the
tram is broken therefore safe to walk. Consistently turn red when tram
approaching.
## Changelog

fix: Fixed timing issue where tram crossing signals would be out of sync
with the moving tram
