>Under TO/TT - a simple "work between" order gave you the right to occupy the main track and move either direction, but with less rights than if you were in yard limits. You had to clear regular trains, and flag both directions against extras that may or may not be there.

Even in yard limits you had to clear superior trains. The Andrews Brothers (Mulford) or Stevie Poo-Poo (Richmond) are going to lay out #11? I don't think so.

>Under TWC - a simple work between gives you the railroad between those points.

"From - to", but not "at" either end named point -- the same is true for running orders. TWC, being based on train orders, is the same.

>I doubt this was used that much without giving the work extra some additional rights or limited relief from flagging against extras.

"Not protecting against .. .. .. " is the applicable phrase to relieve flag protection.

>I have often have trouble following when you had implied right or superiority against another train. If you were ordered to meet another train, the right to the meeting point was implied. But other times, the order did not give you the right to move - even when they couldn't.

Superiority is granted by right, class, and direction; there is no implication involved. If the DS set up a meet between extra trains without specifying which had to take the siding, then fie on the DS (in this rare instance the train moving in the inferior tt direction took the siding).
