- [1] extending in the lengthwise direction, as distinguished from transverse. [2] said of any fore-and-aft structural member, such as a frame or bulkhead.
- Running lengthwise.
- Along the length of a structure.
- Direction parallel to the long axis of an object and perpendicular to its radius — for example, down the length of a cylinder. compare circumferential; radial; transverse. lot tolerance percent defective (ltpd): the poorest quality, in percent defective, individual lot that is acceptable in a sampling plan. ltpd is the percent defective that will be accepted by the sampling plan at most 10 percent of the time. with such a plan, the producer agrees to supply just enough nonconforming product such the consumer will accept the lot using the agreed to sampling plan and acceptable quality level. compare acceptable quality level. lumen (lm): si photometric unit of luminous flux, weighted according to the photopic vision response. one lumen equals the light emitted by one candela (cd) point source into one steradian (sr) solid angle (1 lm = 1 cd/sr).

Lifting points, английский
Marks shown on the sides of a railway vehicle to denote where it is safe to place a lifting device or jack. sometimes referred to as jacking points.
Wheel truing machine, английский
Machine for reprofiling rolling stock wheels. the surfaces of wheels become worn over time varying between months and years depending on the usage and design. reprofiling is required to ensure that the ride of the vehicle continues to be acceptable both from a safety and comfort point of view. if wheel flanges become too sharp, they can force point blades apart and cause a derailment. some machines are designed to permit reprofiling without removing the wheels from the vehicle. the lathe is mounted in the floor of the workshop and the vehicle positioned over it for work to be carried out. the axle end design has to be arranged to allow the wheelset to be turned by the lathe. wheels can be re-profiled by cutting or by milling. cutting seems to be the preferred method for most administrations.
