Plans for a grade separation started in 1965 when the Peninsula Commute was being operated by the Southern Pacific Railroad, but were stymied by the complex geometry of Broadway, which intersects with roads immediately east (Carolan) and west (California) of the level crossing, and (further east) passes over U.S. 101 at an interchange rebuilt ...
By 2020 the junction was the most congested in California, [2] with the level-crossing design contributing to delays throughout the state's rail network. As part of the Valley Rail project, the San Joaquin Regional Rail Commission (SJRRC) and the California Department of Transportation (Caltrans) will grade separate the intersection, which will add capacity for future passenger rail expansion ...
AREMA has 29 technical committees, organized in six functional groups. The committees, whose volunteer members come from the railroad industry, meet on a regular basis and use their expertise to come up with the best methods to maintain a railroad.

Valley Rail is a project to expand Altamont Corridor Express (ACE) and Amtrak California San Joaquins commuter rail services, divided into several segments which include two service extensions from Stockton to Sacramento and Merced, station improvements, and grade separation of the Stockton Diamond.
Other names include railway level crossing, [1] railway crossing (chiefly international), grade crossing or railroad crossing (chiefly American), [2] road through railroad, criss-cross, train crossing, and RXR (abbreviated). There are more than 100,000 level crossings in Europe and more than 200,000 in North America.
Wigwag is a nickname for a type of railroad grade crossing signal once common in North America, referring to its pendulum-like motion that signaled a train's approach. The device is generally credited to Albert Hunt , a mechanical engineer at Southern California 's Pacific Electric (PE) interurban streetcar railroad, who invented it in 1909 for ...
Of the 3,311 public at-grade railroad crossings in Missouri, 1,420 — or 43% — don’t have those devices, according to MoDOT. In the past five years, The Star found that nearly 57% of the ...
Grade-separated pedestrian and cycling routes often require modest space since they do not typically intersect with the facility (such as a highway) that they cross. However, grade-separated pedestrian crossings with steps introduce accessibility problems. Some crossings have lifts, but these can be time-consuming to use.
