the De Winton works in St Helen's Road survives. Since 1988 it has been the home of a local plumbing and heating business; before that the foundry was used as a bonded warehouse and wine merchants. It stands opposite Caernarfon station of the Welsh Highland Railway. The steam engine at Glynllifon was restored by Fred Dibnah after he was originally called to the park to quote for the demolition of the chimney. De Winton locomotives The De Winton records were not preserved, so the complete list of locomotives produced is not known.
