A manual Operator usually cannot control more than TWO trains simultaneously.
A PC running RR&Co TrainController can control 15 or 20 trains simultaneously depending on the design of the particular layout.
This is AUTOMATIC control and involves setting of all turnouts, slips and signals for each individual train
TC also provides a system of Hand Controllers to allow a Manual Operator to run a train MANUALLY in between all the automatically running trains.
