Exhibits J, Grade Crossings Standards Manual - Metrolink

NOTES:1. THESE STANDARDS ARE NOT INTENDED TO REPLACEEXISTING REGULATORY STANDARDS, NOR TO BE ASUBSTITUTE FOR ENGINEERING KNOWLEDGE,EXPERIENCE AND JUDGMENT, BUT ARE REQUIREMENTS,WHICH ARE MOST IMPORTANT FOR SAFE CONSTRUCTION,MAINTENANCE AND OPERATION OF PEDESTRIAN FACILITIESAT HIGHWAY-RAIL GRADE CROSSINGS. SINCE THE ACTUALDESIGN WILL TYPICALLY BE SITE SPECIFIC, INFORMATIONSHOWN ON THIS DRAWING WILL BE MODIFIED AS NECESSARYIN CLOSE COLLABORATION WITH SCRRA.2. FOLLOW CALIFORNIA MUTCD FOR STRIPING, SIGNING, ANDOTHER TRAFFIC WARNING DEVICES.3. REFER TO THE FOLLOWING FOR ADDITIONAL DESIGNINFORMATION:a. SCRRA ENGINEERING STANDARD ES4201 FOR CONCRETEPANELS AND PAVED END RAMP.b. SCRRA ENGINEERING STANDARD ES5101 FOR INTER-TRACK FENCE.c. SCRRA ENGINEERING STANDARD ES5107 FOR SECURITYACCESS GATE, K-RAIL AND BOLLARDS.d. SCRRA ENGINEERING STANDARD ES4001 FOR TRACKSECTIONS AND ASPHALT CONCRETE PAVEMENT DETAILS.e. SCRRA ENGINEERING STANDARD ES4002 FOR SWINGGATE DETAILS.f. SCRRA ENGINEERING STANDARD ES8308 AND ES8309FOR PEDESTRIAN WARNING DEVICES.g.
