 The platform extensions are of a similar construction as the original platform; the only difference in their construction is that the slate used on the extensions was not from the Bryneglwys quarry.The platform surface of the entire platform, including the extensions, was changed during the construction of the platform extensions; the platform now has a tarmac surface (the slate slab edging was not changed).In 1987, the platform was widened, and the surface renewed again.
