Transports Metropolitans de Barcelona has developed TMB Maps, an iPad app which enables users to plan metro and bus trips, locate stops and check the next departure using a tablet computer.

Scottish operator ScotRail is using a desktop train simulator from games publisher RailSimulator.com for route familiarisation and training.
LEM has launched the ITC series of transducers for galvanically-isolated high-precision current measurements in rail applications including traction motor control and energy metering. The company says it determined that Hall-effect measurements could not provide the desired accuracy, so it has used its closed-loop fluxgate experience to develop accurate and linear systems immune to external magnetic fields.
