The biggest obstacle is the signal system that governs train movement.

Modern technology has generally reduced the labour required per train movement.

A main signal controls a train movement along a running line.

The line has also been used for exceptional train movements, including:

At its peak in the 1920s, there were 282 train movements daily.

Signals may not be operated to permit conflicting train movements to take place at the same time.

The line went into operation on April 15, 2002, and reached a peak of 60 train movements per day in October 2006.

The timetable thus provides the basic framework for train movement on a particular portion of the railroad.

The tramway had been built in 1896, and a ground frame was installed to control conflicting train movements.

The support of family preservation can be traced back to the negative reaction to the 'orphan train movement'.
