Abstract

Sections of a highway crossing over the rail road are raised completely clear of the rail road to form a barrier preventing automobile traffic from entering the rail road when a train is at or nearing the crossing. When the train has passed, the barrier sections are lowered, reforming the grade crossing so that automobile traffic may cross the rail road at near grade. The ends of each barrier transverse to the centerline of the roadway are shaped and positioned so that a continuous surface is formed when the barrier sections are in the lowered position, partly resting on the rail road or nearby supports, allowing automobiles to continue over the rail road by means of driving on the upper surfaces of the lowered barriers, with only small gaps at the joints where the sections adjoin each other or meet the approach roadway.

Claims

1. A railroad and highway crossing system comprising:

at least one railroad having two rails and a longitudinal center line between said two rails,

at least one highway crossing said railroad, said highway including a barricade system crossing said railroad,

said barricade system including two sections, each said section having one end adjacent an end of the highway and pivotally mounted on a horizontal pivot, and having a second end terminated at the longitudinal center line of said railroad,

said sections having a raised position to block highway traffic crossing the railroad, and a lowered position to allow highway traffic crossing the railroad, and

each said section, in the lowered position, being supported at the second end directly on the rail.

3. The system according to any one of claims 1 and 2, wherein the horizontal pivot is a bearing.

4. The system according to any one of claims 1 and 2, wherein the support structure is a pedestal.

5. The system according to any one of claims 1 and 2, wherein automatic control means are provided to lower and raise the sections of the barricade system.

2. A railroad and highway crossing system comprising:

at least one railroad having two rails and a longitudinal center line between said two rails,

at least one highway crossing said railroad, said highway including a barricade system crossing said railroad,

said barricade system including two sections, each said section having one end adjacent an end of the highway and pivotally mounted on a horizontal pivot, and having a second end terminated at the longitudinal center line of said railroad,

said sections having a raised position to block highway traffic crossing the railroad, and a lowered position to allow highway traffic crossing the railroad, and

each said section, in the lowered position, being supported at said second end directly on at least one support structure sitting on the longitudinal center line of the railroad.
