I believe what you are seeing from the FRA is political posturing, and job justification.
We already have rules that address lining back main line switches in dark territory…the conductor must inform both the engineer and dispatcher he has done so, and if possible, the engineer or the brakeman must visually see the switch lined correctly and or get verbal confirmation it is lined correctly.
Shoving rules changed last year, in yards, you can only shove half the distance or number of cars a yard track can hold without point protection, any more than half, and someone from your crew has to be either riding the point, or in a position where he has continuous visual contact with the point the entire move.
For my railroad, we added in a rule where, if you are shoving an industry, regardless of how many cars your holding on to, a crew member will be riding the point the entire shove…one car or one hundred, makes no difference.
The GCOR addendum states a crew member has to have visual contact the entire shove, but we decided to play it even safer than that.
As for addressing crew fatigue, don’t hold your breath.
