This relates to Open Rails New Year Monogame version 167.1 (I haven't tried earlier versions of OR NYMG yet) only. Doesn't seem to occur while running Open Rails testing version 1.5.1 - 2012.
While running under OR NYMG version 167.1, on resuming saved activities, I've noticed that the Projected Speed value (as shown on the Track Monitor (F4 key)) drops substantially down in value (by values as much as 5 or more mph), and goes back up in value a bit, and then drops back down in value again and repeats. Prior to saving the activities, the Projected Speed values were relatively stable, and were actually slowly increasing in value as trains were still accelerating.
I presume this Projected Speed fluctuation is due to some bug in OR NYMG version 167.1(?).
