The Lionel 1015 Transformer was available from 1956 until 1960. It was issued with Lionel’s more economical sets during these years. It generated 45 Watts of power and would control one train. There are two variations:
Variation A: The Lionel Service Manual defines this variation as No. 1015-25. It did not have a circuit breaker. Nor is there a directional button to reverse the direction of the train. This transformer was included in many uncataloged sets that featured the No. 246 Locomotive that had a two position directional control. Lionel included a No. 80 Controller with these sets to compensate for this lack of directional control. Produced from 1956 until 1959.
Variation B: The Lionel Service Manual definces ths variation as No. 1015-60. The right terminal has a push button control that changes the direction of the train. See the close-up picture below right. This variation is also not equipped with a circuit breaker. For more information concerning the use of circuit breakers in Lionel’s smaller transformers see: No. 91. We’ve shown the No. 1015-61 Instruction sheet for this variation below. Produced in 1960.
This transformer was replaced by the No. 1025 in 1961. According to the Lionel Service Manual the cover & circuit breaker assembly for this transformer (Part No. 1025-2) can be retro fitted to the No. 1015 to equip this transformer with a circuit breaker.
