rights of trains

[NW Mailing List]

Train orders were also used in automatic block signal  (ABS) territories.  
Much of that territory has been replaced by  absolute block systems.  Signal 
systems needed to include remote or  centralized traffic control (CTC) to 
eliminate operational train orders.   Some roads continued to use train 
orders with an appropriate clearance card to  promulgate other requirements such 
as slow orders, etc.

The  Punkin' Vine still used train orders to make meets even with automatic 
block  signals. This was up until it was CTC'd.

My understanding of TimeTable and  Train Order operation is it is for dark 
(unsignalled) territory.  Once  signals came a new set of rules came and 
when a train could go and stop and  all else.  We didn't need TT&TO any 
more..sort of what  mechanization did to the labor force.  So for the N&W 
Shenandoah  Division mentioned, once signals were there...
The NMRA Operations Special  Interest Group has reprinted a book called 19 
East Copy Three  which goes  in depth about TT&TO
