 The GWR insisted on some of the sharpest curves being eased before they took on the working.Time went by with limited progress, but a Treasury grant of £10,000 was made in April 1910, and the GWR was persuaded to fund the final stages of construction itself.The line was considered to be ready for opening between the junction near Lampeter and Ystrad in June 1910, but before arrangements were made for the Board of Trade inspection, the Great Western Railway asserted their position that the line was not satisfactory from their point of view, and they insisted on delaying opening until the whole line was ready.
