Light Rail Vehicles Public Transit.
LRVs are distinguished from rapid rail transit (RRT) vehicles by their capability for operation in mixed traffic, generally resulting in a narrower car body and articulation in order to operate in a traffic street environment. Due to their large size, large turning radius, and often an electrified third rail, RRT vehicles cannot operate in the street. Since LRT systems can operate using existing streets, they often can avoid the cost of expensive subway and elevated segments that would be required with RRT.

Velvia is a brand of daylight-balanced color reversal film produced by the Japanese company Fujifilm. The name is a contraction of "Velvet Media", a reference to its smooth image structure. It is also known as RVP, a classification code meaning "Reversal/Velvia/Professional series".

Velvia was introduced in 1990 and quickly replaced Kodachrome 25 as the industry standard in high-definition color film. It had brighter and generally more accurate color reproduction, finer grain, twice the speed, and a more convenient process (E-6). Kodachrome 25 fell out of popularity a few years after Velvia was introduced, and Kodachrome 64 and 200 have followed more slowly. Many photographers credit Velvia with ending the Kodachrome

Velvia has very saturated colors under daylight, high contrast, and exceptional sharpness. These characteristics make it the slide film of choice for most nature photographers, including such respected artists as John Shaw, Steve Parish, and the late Galen Rowell.

Shaw, who is known for his extreme close-ups of flowers, has praised the film for its accurate reproduction of the color purple, which has been a difficult color to accurately capture on other films. This was a major issue with Kodachrome, which tended to render purple objects as blue.

Velvia's highly saturated colors are, however, considered overdone by some photographers, especially those who don't primarily shoot landscapes. Its tendency to oversaturate skin tones makes it unsuitable for portraits, because it gives pink or brown skin a red cast. Velvia is referred to as "Disney-chrome" or "Crayola-chrome" by some detractors.
