====Turnaround times====
Most of them have cabs at both ends, resulting in quicker turnaround times, reduced crewing costs, and enhanced safety. The faster turnaround time and the reduced size (due to higher frequencies) as compared to large [[locomotive]]-hauled trains, has made the MU a major part of [[Commuter rail|suburban]] commuter rail services in many countries. MUs are also used by most rapid transit systems. However, the need to turn a locomotive is no longer a problem for locomotive-hauled trains due to the increasing use of [[Push-pull train|push pull train]]s.
