2019-04-30 PLE Ph 2 Train Test Notice_LLB - Copy


THIS Sunday, June 2, the Construction Authority will be testing a newly installed underground communication system for the freight train system that runs through the cities of Glendora, San Dimas, La Verne and Pomona, requiring stoppage of all traffic across the rail corridor for approximately 3-5 minutes each test run, with the possibility of longer delays. The testing will require a freight train (Metrolink or BNSF train) to run at 40 miles per hour (MPH) between Lone Hill Ave in Glendora and Wheeler Ave in La Verne. The testing involves several trials on the active freight corridor to ensure the new communication system will activate and deactivate the train signals at all street crossings. Additional streets east and west of those being tested will also be impacted to allow the train to accelerate and decelerate; see the list below.

The communication system’s testing is part of the initial construction activities for the Foothill Gold Line light rail project being built from Azusa to Montclair.


Train testing will take place this Sunday, June 2, 2019, from 10:00 AM to 8:00 PM.


Intersection/rail crossings affected during the testing include:

City of Glendora: Elwood Ave., Loraine Ave., Lone Hill Ave. and Gladstone Ave.
City of San Dimas: Gladstone Ave., Eucla Ave., Bonita/Cataract Ave., Monte Vista Ave., San Dimas Ave., Walnut Ave., San Dimas Canyon Rd.
City of La Verne: San Dimas Canyon Rd., Wheeler Ave., A St., D St., E St., White Ave., Fulton Ave.
City of Pomona: Fulton Ave. and Garey Ave.


  • Expect 3-5 minutes of delay at the railroad crossings periodically throughout the day, with the potential for longer delays.
  • A Metrolink or BNSF train will begin on the west side (in Glendora) or the east side (in Pomona) of the testing segment and accelerate to 40 miles per hour through all crossings in San Dimas and some crossings in La Verne, activating the train signals and crossing gates at all street crossings (see list above). Once the train reaches the end of the testing segment, another trial run will begin in the opposite direction. A total of six successful runs complete the testing, which could require the testing to occur from 10:00 AM to 8:00 PM.
  • Testing will take place this Sunday, June 2, 2019.
  • The train’s horn will be sounded as it approaches each street crossing.
  • Safety officials, called Flaggers, will assist with traffic management at the intersection/rail crossings being tested between Lone Hill in Glendora and Wheeler Ave in La Verne as the train passes.
  • Pedestrian access via the sidewalks will remain open; however, pedestrian traffic will also be stopped when the train is approaching.
