Ralph, previously Ralph Sadler, after the Snowdon Mountain Railway's consulting engineer, from 1964 to 1977, and Aylwin from 1977 until October 1978, is the seventh engine on the Snowdon Mountain Railway.


Alaric is based on Ralph. Ralph was manufactured by the Swiss Locomotive and Machine Works at Wintherthur, Switzerland in 1923.

As of 2015, Ralph has been withdrawn from service, his boiler has been scrapped, dismantled and stored off-site. It has been stated that it is very unlikely that the engine will be repaired and resume service, meaning it is very possible the locomotive may be scrapped.


Alaric was painted green with red lining.
