An extendable railcar work platform includes one or more work platform sections each including a set of wheels, a locking mechanism associated with each wheel and a guide system. The system enables workers to safely work above an electrified third rail such as in a subway or railway tunnel. The platform may be in a first retracted position for transit or in a laterally extended or vertically extended position to enable a worker to access and work on a tunnel wall. The platform may be extended to both sides of the railcar and, if the platform includes more than one section, the individual sections may be simultaneously extended to opposite sides of the railcar. Each work platform section includes a floor or base and safety rails around all four sides of the section.
