I was wondering if a route can have signals without a dispatch, or is a dispatch required when a route have signals? Also, how does Dark Territories usually work?

It used head blocks, and a train would enter it, and then I believe if it was out of cycle (meaning an extra, non scheduled move) a train would enter the head block, and the system would hold the train fora few minutes, while it figured out if there was something ahead, and if not, it would automatically give it railroad by changing the direction of traffic. The line is single track and used to only have inbound trains in the AM and westbound trains in the PM, so there was little chance of conflicting moves. where there was freight customers, they used yard limits designation
Dispatchers basically have only control over entrace or crossover switches (the CP's) everything in between is automatic.
Same in manual block a dispatcher or block operator controls blocks via a train order/form D / form M or whatever its called on differet railroads.
instead of train tripping signals, the crew reports clear of limits, which could be switch/block limit/ or leaving territory at end of manual block.
