N.Y. Comp. Codes R. & Regs. tit. 17 § 8C.01
INSERT the following paragraphs:
Standard:
06A When an overhead flashing-light signal is used, the vertical clearance shall be no more than 19 feet above the crown of the highway to the lowest point of the signal unit.
Standard:
12A When used, the devices shall be operated continuously (unless not required by the appropriate operating standards) except as provided in paragraph 12B.
Option:
12B Special control features may be provided for making the devices insensitive to train actuation while trains are performing regular stops or switching operations in the vicinity of a crossing, to prevent excessive activation of the traffic control devices.
Standard:
12C When the Option is enacted, provisions shall be made to ensure that the devices are again made operative for the required time before any rail traffic proceeds over the crossing. Provision shall also be made to ensure that automatic operation of the devices will resume upon the approach of any rail traffic other than the one for which operation of the device was discontinued.
Support:
12D Since grade crossing traffic control devices govern the actions of vehicular and pedestrian traffic, the principles of uniformity and standardization apply to these devices.
Guidance:
12E For the purpose of signal control, crossings more than 100 feet apart should be treated separately.
