Route capacity is maximised for any rail system when all the rail traffic is the same type. Mixing different types of trains, or even different stopping patterns, will result in a substantial reduction of capacity. [ 15 ]
For example, if Railroad A borrows a 2,500 horsepower locomotive from Railroad B and operates it for twelve hours, Railroad A owes a debt of (2,500 hp × 12 h) 30,000 hp⋅h. Railroad A may repay the debt by loaning Railroad B a 3,000 horsepower locomotive for ten hours.
Parts of a driver's work day are defined in four terms: On-duty time, off-duty time, driving time, and sleeper berth time.. FMCSA regulation §395.2 states: [5]. On-duty time is all time from when a driver begins to work or is required to be in readiness to work until the driver is relieved from work and all responsibility for performing work.
The detail found in Working Timetables includes the timings at every major station, junction, or other significant location along the train's journey (including additional minutes inserted to allow for such factors as engineering work or particular train performance characteristics), [2] which platforms are used at certain stations, and line codes where there is a choice of running line.
Headway is a key input in calculating the overall route capacity of any transit system. A system that requires large headways has more empty space than passenger capacity, which lowers the total number of passengers or cargo quantity being transported for a given length of line (railroad or highway, for instance).
The federal hours-of-service law that forbids certain classes of railroad employees, including those operating trains, from working longer than a certain time after reporting for duty, currently 12 hours [141] [142] Hogger A locomotive engineer [38] [71] [134] [143] Honorary steam engine
After several extensions, the Federal Railroad Administration (FRA) announced on December 29, 2020, that PTC was operating on all required freight and passenger rail routes. [6] While PTC’s main purpose is to prevent collisions, it also allows higher speeds in some cases. Different PTC systems are used in various regions across the country.
Railway costing is the calculation of the variable and fixed costs of rail movements. Variable costs are those that increase or decrease with changes in the traffic volumes or service levels and include fuel, maintenance and train crew costs, for example.
