'The rehabilitation of the 24 LRVs will expand capacity which should result in faster travel time because of reduced train headway
and queueing time,' LRMC president and CEO Juan Alfonso said in a statement.
 built a model to maximize the overlapping time between the motoring and braking of successive trains by regulating train headway and dwell time.
Train headway and interstation runtimes are optimized to improve the utilization of RBE as well as reduce the traction energy consumption by allocating the runtime supplements properly.
Meanwhile, for URT, path impedance mainly consists of travel time, comfort, transfer time, train headway, and so forth.
Passenger waiting time is related to the train headway and the time that passengers arrive at the platform.
To deal with the rush-hour crowd, the RTA has also decreased the train headway
on the Red Line to two minutes 38 seconds during peak hours.

Off-peak train headway
will be every four to 10 minutes.
The starting time of the first westbound (WB) train is varied each time by a quarter a of train headway
. This ensures that the positions where the WB trains cross the east-bound (EB) trains are different between staggers.
on open railway lines operates in a spatial gap of the length of two fixed block sections, and the minimal headway is determined according to UIC recommendations.
is an important concept that is directly related to operation safety and the capacity of a metro line.
The upgrade includes the introduction of a new signalling system of 385 jointless track circuits to detect train position, maintain safe separation distances and deliver train headways
capable of meeting the extremely demanding timetable.
