Price in 1953: Unlisted
The finest electric train power controller you can buy! Has features never before incorporated in transformers and with its giant capacity you can run two trains at different speeds on separate loops of track, or FOUR trains (two running at same speed) on four separate layouts. Has full directional control; when train stops it will start up again without going into reverse first. Two panel meters indicate voltage — one for each control. Has green power—on light and two red warning lights that indicate a short circuit. Transformer has "Dead Man‘s Control" as real railroad feature. When throttle is let go, train halts! Operation is guarded by two circuit breakers — one for each controller — which shut off power if over-load or short occurs. Case is high impact material.
