File:X1972 Callendr Rheilffordd Ffestiniog.jpg

Y Cambrian, Y Rhymni, Y Taff, Y Barri—atgofion pell a dogfennau llychlyd yw'r cwmniau rheilffyrdd Cymreig hyn yn awr. Ond mae'r hynaf ohonynt i gyd gyda ni o hyd—Lein Fach Ffestiniog, mam holl reilffyrdd culion y byd. Wedi blynyddoedd lawer o ddirywiad a chyfnod byr o segurdod llwyr, daeth gwaredigaeth yn 1954, a byth er hynny mae pethau'n gwella'n gyson.

The Cambrian, the Rhymney, the Taff Vale, the Barry . . . the Welsh railway companies are now nearly all distant memories and dusty files. But the oldest of them all is still with us—the Festiniog Railway, mother of the world's narrow-gauge lines. After many years of decline and a short period of closure, it was rescued in 1954 and has been on the mend ever since.

Yma gwelir Iarll Meirionnydd, "injian" ddwbl Fairlie a adeilad-wyd yn 1886, yn dod allan o dwnel y Garnedd i haul y gwanwyn. Ymdrech gynnar oedd yr "injian” Fairlie i grynhoi peiriant mawr i le bychan trwy gael boeler ym mhob pen. Methodd peirianwyr oes Victoria ddyfeisio pibellau ystwyth i'r ager redeg drwyddynt gyda'r canlyniad fod peiriannau Fairlie wedi bod yn drafferthus erioed. Ond, yn awr, yn saith degau’r ganrif hon, mae'r broblem wedi ei datrys.

Double Fairlie Earl of Merioneth of 1886 emerging from Garnedd Tunnel in spring sunshine. The Fairlie locomotive was an early attempt to cram a lot of engine into a small space—a double-ended boiler with the driving engines swivelling underneath on bogies. The Victorians failed to discover a flex for steam, so Fairlies have always been troublesome—until now, in the 1970s, reliable steam pipes are becoming available.
