Steam offers various features, such as game server matchmaking with Valve Anti-Cheat (VAC) measures, social networking, and game streaming services. The Steam client functions include update maintenance, cloud storage, and community features such as direct messaging, an in-game overlay, discussion forums, and a virtual collectable marketplace.
Compared to steam, diesel power reduced maintenance costs dramatically while increasing locomotive availability. On the Chicago, Rock Island and Pacific Railroad, new units delivered over 350,000 miles (560,000 km) a year, compared with about 120,000–150,000 miles (190,000–240,000 km) for a mainline steam locomotive.

The maintenance of the new diesel locomotives in filthy steam sheds soon proved difficult and, although some old sheds survived, many new diesel depots were built on new sites or on the sites of the old steam sheds. The major problem was the disposal of oil, which initially was left lying around causing pollution and safety issues.
Stationary engineers are responsible for the safe operation and maintenance of a wide range of equipment including boilers, steam turbines, gas turbines, gas compressors, generators, motors, air conditioning systems, heat exchangers, heat recovery steam generators (HRSGs) that may be directly fired (duct burners) or indirectly fired (gas ...
Particular attention has been given to endemic problems that led to the demise of steam power in small- to medium-scale commercial applications: excessive pollution, maintenance costs, labour-intensive operation, low power/weight ratio, and low overall thermal efficiency; where steam power has generally now been superseded by the internal ...
A steam turbine or steam turbine engine is a machine or heat engine that extracts thermal energy ... Maintenance requirements of modern steam turbines are simple and ...
