The main predictor of dwell times varies widely by mode, time, and line. However, dwell times are usually affected mostly by the number of passengers needing to board and alight from a vehicle. Density imbalance along the platform and between vehicles is mainly due to human and motivational factors (minimising distance and time at the arrival) [7]
The main queueing models that can be used are the single-server waiting line system and the multiple-server waiting line system, which are discussed further below. These models can be further differentiated depending on whether service times are constant or undefined, the queue length is finite, the calling population is finite, etc. [ 5 ]

A train not included in the normal schedule of a railroad. [82] [83] [84] They often run during busy holiday travel periods in order to handle larger crowds and reduce the number of passengers waiting or stranded at a station. In train order territory, extras are required to clear the main line for scheduled trains to pass. [85]
These are explained diagrammatically by the UITP. This list focuses heavily on trains in the classical sense used for large-scale railways for passengers and freight but does include a few people mover systems. For a similar list for GoA2, see list of semi-automatic train systems.
A Class 66 locomotive (right) is waiting at a red signal while a First Great Western (now Great Western Railway) passenger train (left) crosses its path at a junction. Railway signalling (BE), or railroad signaling (AE), is a system used to control the movement of railway traffic. Trains move on fixed rails, making them uniquely susceptible to ...
In train order operation, a "train order" is an order issued by or through a proper railway official to govern the movement of trains". [ 1 ] Train order operation was widely used by the railroads of North America before the days of centralized traffic control (CTC), direct traffic control (DTC), and the use of track warrants conveyed by radio.
