Quickly calculated as: cycle time in the base period divided by headway in the base period. Also referred to as "base period vehicle requirement." Bid – see sign-up Bid package – see rostering Bid sheet – see run guide

Car hours – see vehicle hours Car pooling is the use of an automobile to ferry more than one operator between the garage and a relief location, or even between two relief locations. Check-out time – see clear allowance Clear allowance is the amount of time paid to an operator at the conclusion of the run to turn in transfers, fare media, or other supplies and reports.

Dovetailing – see intertiming Drop-back is a technique where the operator or train crew gets off an arriving vehicle at a terminal, takes layover, and assumes operation of the next vehicle to arrive. Most common on frequent rail lines where close headways do not allow suffi cient layover time for the train crew, this technique is also used for special events to maximize the number of trains in service.

Used interchangeably in this manual with "master schedule," and also known as "recap" or "rotation." Heavy rail is transit service using rail cars with self-contained, selfpropelled motive capability, driven by electric power usually drawn from a third rail, operated on exclusive right-of-way with level platform boarding. Heavy rail generally utilizes longer trains and longer spacing between stations than Light Rail.

But either half of a split run could itself have multiple pieces, cut from multiple blocks. Multipiece straight – see straight run Node – see transit center Non-revenue travel – see deadhead

Also known as "comments." Off -peak period – see base period On-board count – see ride check On-board tally – see ride check On-street relief is the process where, at a specifi c time during a specifi c trip on a block, one operator's run ends and another operator's run begins. The relief may occur at a terminal or at a designated point along the route (possibly close to the garage)

Platform time, a phrase derived from the early ͮͬth century days when motormen and conductors operated from the "platform" of a streetcar, includes all time when the operator is operating the vehicle. Layover time and pull-in and pull-out time are part of platform time, but report allowance and clear allowance, and travel time (unless part of a pull-in or pull-out)

Pull time – see pull-in time and pull-out time Pulse center – see transit center Pulse transfer – see timed transfer Recap – see headway sheet or master schedule Recovery time – see layover time Regular run – see full-time run Rehooking is the process of changing how trips are linked into a block. This is done when evaluating blocks and during the runcutting process.

Revenue hours are the number of hours of service available to passengers for transport on the routes. Excludes deadhead hours, but includes layover time.

The schedule pattern can be repeated throughout the day or can change as running times and layover times change during the day. School extras – see school trips School trips or school service are additional scheduled trips at school bell times to accommodate the heavy loads associated with student ridership along a route.

is usually paid whereas in two-piece split runs the break is generally not paid. Split runs tend to be used to allow both peaks to be covered by one operator since the work day would otherwise be too long for a straight run.

more revenue trips and concluding with a pull-in trip back to the yard. Transfer center – see transit center Transfer window is the layover time scheduled at timed transfer locations to ensure that transfer connections can be made, and may also refer to the amount of time past its scheduled departure time that a vehicle can be held at a transfer location to wait for a late arriving vehicle.

From page 394... ...
See "Service Pattern." A service pattern follows one or more variants. Vehicle hours are total hours of travel by a vehicle, including hours in revenue service (including layover time)
