The line is single-tracked and slow, with a large number of at-grade crossings.

Some at-grade pedestrian crossings go over these roads, but most remain subways or bridges.

In the United States, railroad tracks are largely used for freights with at-grade crossings.

With trains running at higher speeds throughout the route, safety at all at-grade crossings needs to be considered.

Three at-grade crossings with roads remain as of 2009, and all three will be eliminated in a separate project.

The state has indicated it might have to close several at-grade crossings along the route that were considered unsafe.

Speed is a function of the number of at-grade crossings, not the type of vehicle.

Most at-grade crossings in China are for smaller industrial spur and access lines which may or may not have crossing gates.
