A
train meet is the situation in
railroading or
rail transit operations in which or the location where a train traveling in one direction "meets" another traveling in the opposite direction, either while traveling on parallel
double or multiple
tracks, or while stopping and waiting on a
railroad siding for the other train to pass on a
single track mainline. Determining the time and location of where such trains meet is paramount in
railroad engineering particularly in single track sections to avoid
collisions or to allow faster trains to bypass slower service trains.
