However, the Circle is also keenly aware that much of the early railway heritage of Wales is at risk of being lost through decay and neglect along abandoned routes or modernisation on the current network, or that records made by earlier researchers may exist but are currently unavailable to a wider audience.

This has become all the more apparent as more and more significant "anniversaries" occur in the railway world, and so the Circle has launched a series of initiatives to attempt to protect or record sites and documents before they are potentailly lost forever.
