StopGate System
The StopGate™ Barrier Arm can help to prevent vehicle intrusion onto the railroad grade crossings by vehicles up to 4410 lb. (2000 kg) traveling at speeds up to 43 mph (70 km/h). When interconnected to standard railroad signal circuitry, the StopGate Barrier Arm closes the crossing when needed to provide for safe train pass-through. The StopGate Barrier Arm operates like a standard automatic warning gate using the interconnect signal to raise and lower the arm. Unlike a standard crossing device, the StopGate Barrier Arm completely spans across the roadway, and connects to a locking device on both sides of the road, creating a positive, crashworthy barrier..

Upon vehicle impact, the StopGate Barrier Arm acts as an arresting system to bring a vehicle to a complete stop. The StopGate Barrier Arm has successfully passed the NCHRP 350 TL-2 tests as required using vehicles weighing both 1808 lb. (820 kg) and 4410 lb. (2000kg) for structural adequacy, occupancy risk, and vehicle trajectory evaluation criteria at speeds up to 43 mph (70 km/h).
StopGate Barrier Arms are custom designed for each application. The following are general specifications for a typical StopGate Barrier Arm:
Overall Length (with 55 ft. arm) 67 ft. (20.4 m)
Housing Dimension 2.5 x3 x5 ft. (.8 x.9 x1.5 m)
Required Clear Zone To Railroad Tracks 17 ft. (5.1 m)
Maximum Length Of Arm Structure 55 ft. (16.7 m)
Post Impact Repair Time* Approximately 2 hours
Voltage Requirement 12 or 24 V
*Based upon a design impact, repairs should be done by a 2-man crew

The StopGate Barrier Arm incorporates annealed stainlesssteel cables laced together into a net-like structure and is designed to diffuse the kinetic energy of an impacting motor vehicle.The StopGate Barrier Arm helps to stop the vehicle from penetrating onto the railroad tracks and colliding with a train.
