In pursuance of the powers vested in it under Sections 256, 257 and 287 of the Railway Act, and of all other powers possessed by the Board in this behalf and upon the report and recommendation of the Chief Engineer of the Board—

It is ordered that, until further notice, the specifications for signals of the wigwag type at highway crossings are and shall be as follows:—

  1. Mounting.
    1. The assembly and painting of apparatus shall conform to the Board's drawing entitled "Highway Grade Crossing Signals of Wigwag Type," dated August 10, 1945.
    2. The "Railway Crossing" sign and signal shall be mounted on the same post.
    3. A signal shall be placed on each side of the track.
  2. Operating time.

    Automatic signal devices used to indicate the approach of trains shall so indicate for not less than twenty seconds before the arrival of the fastest train operated over the crossing.

  3. Circuits for automatic operation of wigwag signals shall be so arranged that signals will operate until rear of train reaches or clears the crossing.

  4. Lights.

    Signal lights shall shine in both directions along the highway.

  5. Lenses or Roundels.

    Lenses or roundels shall be five inches diameter and shall be in accordance with A. A. R. Signal Section Specification No. 69.

  6. Range and Spread.

    The signal light, when the disc is suspended vertically, shall have a range, at night, of fifteen hundred feet through a total angle of not less than 30 degrees when a 10-watt lamp rated at 1,000 hours is burned at rated voltage.

  7. Cycles.

    Movement from one extreme to the other and back constitutes a cycle. The number of cycles per minute shall be 30 minimum, 45 maximum.

  8. Bell.

    Bell shall be used when specified and shall be in accordance with A. A. R. Signal Section Specification No. 44.

  9. Every highway crossing signal upon the line of any railway company subject to the legislative authority of the Parliament of Canada, installed for the purpose of protection, shall be efficiently maintained by the railway company upon whose line the protection is installed, and shall be inspected at frequent intervals, but the interval between such inspections shall not exceed a period of forty-eight hours, and the method of test shall be such as will indicate whether or not the signal is in good working order. If the highway crossing signal fails to operate, or operates continuously, a flagman shall be placed at such crossing at once, whose duty it shall be properly to protect the same until such highway crossing signal is repaired. Notice of such non-repair shall be given at once to the station agent nearest to such highway crossing signal, whose duty it shall be to report the matter at once to the department having charge of the operation and repair of such highway crossing signals.
  10. That in any case where the Board orders a highway crossing signal to be installed, a plan showing the layout must be filed for the approval of an Engineer of the Board.
  11. That failure to place a watchman as required by these regulations will subject the defaulter to a fine of $50, payment of which may be ordered by the Board upon proof of the offence.
  12. That General Orders Nos. 468, 521 and 553, dated respectively March 12, 1929, November 2, 1933, and March 26, 1936, made herein, be, and they are hereby, rescinded.
