Comment 2 for bug 1629635

A partial bug fix has been uploaded in x.3934, accordingly to http://www.elvastower.com/forums/index.php?/topic/29082-trainbrake-problem-with-acela-hhp-8/page__view__findpost__p__224482 .
What remains to be solved is that on single-pipe locos, in the decelerating phase where the dynamic brake does no more intervene enough because of fadeoff, the airbrake does not resume operation.

To temporarily overcome this, the player has to slightly increase brake percentage.
