Official Idling Policy

So here's the policy as it is officially written:

OC Transpo Hot and Cold Weather Bus Idling Procedures
OC Transpo City of Ottawa
4 of 5
4.0 Standard Operating Procedure
This procedure applies to OC Transpo buses at lay-up points. Idling requirements are based on the outside ambient temperature, as reported by Environment Canada, as follows:
i. Temperatures below -5˚C (degrees Celsius) – Do not shut the bus off. All buses are to be kept running to avoid start-up problems. Bus operator is to place the transmission in neutral, apply the Spring/Parking Brake and let the bus idle on “Fast Idle”
Please Note: All buses are to have the “fast idle” switch in the „ON‟ position when idling. If the switch is in the on position when the bus is parked, the switch may need to be toggled off and back on to activate the fast idle, as the default is low idle regardless of switch position
ii. Temperatures above -5˚C (degrees Celsius) – All bus engines are to be shut down when lay-up is expected to exceed seven minutes, as follows:
Observe a three minute high idle shut-down procedure – let the bus idle, in neutral, with the “fast idle” switch in the „ON‟ position, for three minutes before shutting down the engine
Observe a three minute high idle start-up procedure – let the bus idle, in neutral, with the “fast idle” switch in the „ON‟ position, for three minutes before departure
Please Note: All buses are to have the “fast idle” switch in the „ON‟ position when idling. If the switch is in the on position when the bus is parked, the switch may need to be toggled off and back on to activate the fast idle, as the default is low idle regardless of switch position
As stated in the Vehicle and Equipment Idling Policy, exceptions to this procedure exist only under the following circumstances:
For vehicle maintenance and diagnostic purposes (to be kept to an absolute required minimum)
Under extreme weather conditions or any other time when the health and safety of employees or others may be jeopardized
Standard Operating Procedure

Seven minutes is the official cut-off for whether I'm supposed to shut my bus off between -5C and 25C.

That's a half a litre of wasted fuel. On my Sunday work, that's 5 full litres of wasted fuel over a ten hour shift. In 52 weeks, that's 260 litres of wasted fuel, and I work 5 other days in those weeks that I'm not counting.

I had planned a blog about fuel savings based on my idling time for the end of this year, as I have been tracking my idling time since January. I estimate that I have already saved 145 litres of fuel this year by shutting my bus down as soon as I can at the end of each line. I have never had a problem starting it.

7 minutes is a big deal when 1000+ buses are idling through it.
