The term mass transit generally refers to passenger vehicles that are common carriers in urban areas, as distinct from intercity travel. The terms public transit or simply transit also are frequently used. The major types of public transit are bus (rubber-tired vehicles), rail (running on tracks), and ferryboat. Within each type there are several subcategories.

Surface friction is a source of rail s advantages in transport energy efficiency. Under similar conditions, steel wheels on steel rail generate only abont 20 to 30 percent of the rolling friction that rubber wheels on pavement generate, both because rails are much smoother than paT. cnicnt and because steel wheels arc much more rigid than rubber tires, so steel wheels deform much less at the point of contact with the gi ound. Each rail wheel has only about 0.3 sq in of surface in contact with the rail, whereas an automobile... 

The first commercially successful pneumatic tire was developed in 1888 in Belfast by the Scottish veterinarian John Boyd Dunlop primarily to improve the riding comfort of bicycles. Dunlop also showed, albeit qualitatively, that his air-inflated pneumatic took less effort to rotate than did the solid rubber tires in use at that time. His qualitative tests were the first known rolling resistance experiments on pneumatic tires. Due to this significant reduction in rolling loss, many professional cyclists in Britain and Ireland adopted air-inflated tires for their bicycles by the early 1890s. Pneumatics for the nascent automobile industry soon followed.

Process particulate pickup may significantly increase the risk of boiler foaming. This kind of problem happens in the crossover of hot to cold water during manufacturing processes, as in rubber tire factories, food can cookers and retorts, plastic injection molding, and the like). 

In certain processes (such as rubber tire manufacture and plastic injection molding operations), it is common for a valve sequencing system to first provide hot steam followed by cold cooling water and thus for cross-contamination to occur. The result may be the stripping of passivated cooling system surfaces by steam and for the condensate to be infiltrated by cooling water.

It wasn t until 1874 that the first truly modem bicycle appeared on the scene. Invented by another Englishman, H. J. Lawson, the safety bicycle would look familiar to today s cyclists. The safety bicycle had equal-sized wheels, which made it much less prone to toppling over. Lawson also attached a chain to the pedals to drive the rear wheel. By 1893, the safety bicycle had been further improved with air-filled rubber tires, a diamond-shaped frame, and easy braking. With the improvements provided by Lawson, bicycles became extremely popular and useful for transportation. Today, they are built, used, and enjoyed all over the world.
