Commercial vehicles. In road vehicle design, cab forward, also known as cab-over, COE (Cab Over Engine), or forward control, is a body style of truck, bus, or van that has a vertical front or "flat face", with the cab sitting above the front axle. This body design allows for a more compact configuration.
Despite the advent of electric and diesel locomotives in the mid-20th century, steam locomotives continued to be used and constructed into the 21st century. Steam locomotives constructed in the 21st century fall into two broad categories: those that use advanced steam technology to be commercially competitive with diesels; and those built to ...
The Pennsylvania Railroad (PRR) class T1 duplex-drive 4-4-4-4 steam locomotives, introduced in 1942 with two prototypes and later in 1945-1946 with 50 production examples, were the last steam locomotives built for the PRR and arguably its most controversial. They were ambitious, technologically sophisticated, powerful, fast and distinctively ...
