3. These Specifications apply to every electronic track scale intended for use in trade for the in-motion weighing of railway cars.

• 4. (1) A track scale shall be provided with wheel detectors that

  • (a) initiate any logic sequence required to determine train velocity and axle configuration of railway cars and any other monitoring required for in-motion weighing; and

  • (b) permit the detection of any false logic or other malfunction that interferes with the proper operation of the track scale.

• (2) Where any false logic or other malfunction is detected, the track scale shall become inoperable.

5. A track scale shall be designed to have a static operating mode and a dynamic operating mode and to indicate the operating mode selected.

6. A track scale shall be designed so that dynamic adjustment of a weight does not affect any adjustment in the static operating mode.

7. A track scale shall be designed so that the means provided to make coarse zero and span adjustments in the static and dynamic modes are sealable.

8. The means that is provided for dynamic adjustment in a track scale shall have a maximum range not exceeding 0.25 per cent of the capacity of the track scale.

9. A track scale shall be designed so that while operating in the static mode it provides weight registrations with a minimum increment of 10 kg or less.

10. Where a track scale is being used in a manner other than in the manner authorized by the approval issued pursuant to section 3 of the Act or by the certificate issued pursuant to section 19 of the Act, the registration of the track scale shall be accompanied by a statement indicating that the registration shall not be used in trade.

11. Where a track scale incorporates a printer,

• (a) means shall be provided to prevent a keyboard entry from altering data that has been entered or is being entered in respect of the in-motion weighing of a railway car;

• (b) every keyboard entry of weight data shall be accompanied by a statement indicating that it is a keyboard entry;

• (c) the printer shall indicate the operating mode of the track scale when used for any purpose other than in-motion weighing;

• (d) the printer shall provide a printed record that

  • (i) includes the date and time of entry,

  • (ii) the identification number and weight of each railway car, and

  • (iii) subject to subsection 12(1), the total gross weight of the railway cars where summation of net weights is required;

• (e) means shall be provided to prevent printing of the weight of the locomotive;

• (f) means shall be provided so that on completion of the in-motion weighing of a railway car and the printing of the weight of the railway car, all stored weight data in respect of that railway car is automatically cleared; and

• (g) the weight corresponding to the tare of a railway car shall be accompanied by the words “actual tare” or “tare réelle”, or the words “stencilled tare” or “tare inscrite au pochoir”, as the case may be, where that weight is printed on a record.
