10 miles of 10 MPH sounds excessive - I don't think a Tie & Surfacing gang can work 10 miles in a day - even a 12 hour day.

Not sure MOW is subject to the 12 hour rule (according to a Metro North story I read recently). Maybe the C&E have to get switched out if it's a "work train," but if it's all "track equipment" (i.e., not locomotive and railcars, but self-propelled track machines) they might be able to exceed 12 hours (and earn lots of overtime in the process, the trigger for the Metro North story).

MofW are not affected by the HOS law. However, their normal production in a 12 hour day is 3 to 4 miles.

OK, but the "hour of 10mph running due to a current slow order" may not have been related to how much track had been "worked" by a T&S gang, but by how long a stretch of track *needs to be* worked on. I don't necessarily see the connection to a T&S gang or how much track it can work on in a day of however many hours.

The other thing that enters into the picture is how much 'tonnage' operates over the track that has been surfaced (had the track/ballast structure disturbed). Since routine freight operation over this line is rare, I don't know how many trips of the SWC over the disturbed track would constitute sufficient tonnage to permit speed restrictions to be raised back to normal operating speeds.
MofW gang does 3 miles today, 3 miles tomorrow and 3 miles the day after and with the light traffic volume you now have 9 miles of 10 MPH. The tonnage traffic and low speeds are what compacts the disturbed track structure into a solidly based track that will support maximum authorized speeds.
