Mr Hawkeye is right on, but the speed limit on No. 2 between Wood River and Lenox is 79, not 60. Or at least it was a couple of years ago, when I was running down there. It is indeed 30 between Lenox and WR Tower (nee Granite City).
No. 2 is bidirectionally signaled, but that doesn't really help things a whole lot. You don't want to "wrong main" going south, because the schedule doesn't really allow for that seven miles of 30mph between Lenox and WR.
One other note is that, going south, you ALWAYS get an Approach signal at 272.7 - Pontoon Road - in advance of the Restricting (or Stop) at WR Tower. Per KCS rules, an Approach requires "immediate" reduction to 30mph. If you're on No. 1, that's a fairly healthy distance to be doing 30 when you could be doing 79. Of course if the engineer wants to make up a minute he can always apply his own definition of "immediate"
- but that opportunity has been negated by a semi-permanent slow order of 30 or 25 at the ex Pontoon Road crossing. It might finally be gone, now, but I'm not sure.
And of course, the speed limit through Lenox is 30 on No. 1 south (max 20 north, due to Restricting indication) and 10 over the puzzle switch there on No. 2. The turnout at Wann from No. 2 to the single track is 15. And the Wood River diamonds are 40 on No. 1, 25 on No. 2. There are a whole bunch of low speed areas on this stretch of track that need to be rectified.
