Steam locomotives of the 21st century fall into two broad categories: those that use advanced steam technology and are designed to be commercially competitive with diesel locomotives; and those built to more traditional designs for hauling tourist trains. Even locomotives in the second case likely use some modern methods and materials. These include welded boilers, to simplify construction, and roller bearings to improve reliability. For safety reasons, asbestos is not used for boiler lagging and is replaced by other materials, such as glass fibre. If the locomotive runs on main lines, safety systems such as the Train Protection & Warning System (TPWS) and an On-Train Monitoring Recorder (OTMR) must be fitted.
