This is the MRC Tech 4 Model 220 with 16VA and MOME Train Controller.

FEATURES: Combines the momentum feature of the model 1500 and has the power
            of the model 2400.
          (MOME) Momemtum or flywheel action switch contains a delay circuit
            that mimics the lag time of speeding up or braking of real trains.
          Pressure brake provides gradual steady deceleration.
          Proportional Tracking Control (PTC) provides responsive, realistic
            model train operation
          Accutec Technology monitors feedback from layout and kicks in to
            detect sudden changes in loads, then audits your throttle setting
            and compensates for the new demand by delivering the needed
            power output.
          Three hundred degree speed control range gives you three times the
            control arc of ordinary power packs.
          Automatic Circuit Protector disconnects your equipment if continued
            overload occurs.
          AC accessory terminals.
          Operates HO, N, O, S, Z and other scale DC trains.
