Jones Bros of Ruthin are the contractors for the first phase of the £1 million project which will see 260 metres of the embankment, built in 1811, widened to allow the construction of a second platform at Porthmadog Harbour Station. This will enable trains from both the Ffestiniog and Welsh Highland Railways to use the station simultaneously.
When the work is complete, in time for the 2013 season, the improvements will allow the railway to offer a much-improved service for passengers, with cross-platform interchange between Blaenau Ffestiniog and Caernarfon trains.
The rock delivery phase will be completed by mid-February.
Construction work got underway soon after midday on Wednesday January 11th with five lorry loads of stone tipped in the first half hour.
The basic plan is that a trench is dug in the sand which is then covered with a plastic membrane on which the rock is placed. During low tides the area of work will be able to extend with further sections of membrane laid and sufficient rock placed to get above most of the higher tide water levels. Then when the tide is in work will move back to increase the height of sections that have already seen that initial depth of rock cover.
