Traeth Mawr The Croesor Tramway ran from the wharves at Porthmadog to the quarries at the head of Cwm Croesor. The southern end of the line connected to the Ffestiniog Railway near a timber yard at Cornhill. The line swung to the north and ran through the western edge of the town. North of the Snowdon Mill it crossed the Cambrian Railways Machynlleth-Pwllheli line on the level before heading north across Traeth Mawr - the great polder behind The Cob. A short standard gauge branch from Porthmadog Station ran on the western side of the tramway to meet the narrow gauge at Beddgelert Sidings. This was an interchange point where much of the slate from the quarries was transferred to the Cambrian for shipment onwards. From Beddgelert Siding, the line ran north east across Traeth Mawr. It crossed the Afon Glaslyn a mile north of Porthmadog. This was initially a wooden bridge, though later it was replaced with a substantial stone bridge that carried both the railway and the road over the river. The road and railway ran parallel almost as far as Croesor Junction. Croesor Junction did not exist before 1901, when the tramway was purchased by the Portmadoc, Beddgelert and South Snowdon Railway. After 1901 it became the junction between the tramway heading north east and what would become the Welsh Highland Railway heading north west. The tramway continued to Pont Garreg-Hylldrem where it ran alongside the Afon Maesgwm for a short distance. Here the tramway climbed the first of a series of inclines into Cwm Croesor. Inclines to Croesor village The first incline, the Lower Parc incline, rises around past Beudy-Newydd farm house. At the top of the incline the tramway turns through a tight s-bend and immediately arrives at the foot of the Upper Parc incline. This rises another and ends in a winding house that straddles the tramway - this has been preserved and converted into a home. The tramway continues to run north-east entering the village of Croesor where is crosses the main road into the village on the level. Cwm Croesor North from the village, the line crosses Afon Croesor on a low slate-built bridge then continues along the bottom of Cwm Croesor. The valley floor here is nearly level and the line travels almost straight to the north east. Apart from a shallow cutting near Croesor Uchaf farm, this section of the
