From Mogg's Great Western Railway and Windsor, Bath and Bristol Guide, 1851

At 3¾ miles from Bristol, the Railway enters an excavation, carried through which it passes, at 4½ miles from that city, unseen, upon the right, Ashton Watering, a little beyond which terminates the rise of 1 in 440 upon which it has to that point been constructed. Here the Bristol and Bridgewater Road crosses the line. It now commences a descent of 1 in 374 feet, and, carried through a deep cutting to an archway of 300 feet in length, it arrives at Flax Bourton, 6 miles from Bristol. From Flax Bourton ¼ mile beyond which it crosses the road to Wraxhall, and in rather more than half a mile the road from Farley to Nailsea, it is constructed with a gradual bend, chiefly through cutting, to very near the 7 milestone, when it enters on an embankment that carries it to The Backwell Station an intermediate one, distant from Bristol 8 miles, from Exeter 67½ miles, from London 126 miles. The Backwell Station is situate at the Backwell and Nailsea road, the former a considerable village, about 1 mile distant on left, the latter a large village, about 1 mile distant on right. Nailsea is situate in the centre of the great coal field to which it gives name, and, extending in various directions to a great distance, proves a fruitful source of revenue to its proprietors. The Bedminster coal field, it may here also be remarked, is traversed for some time after quitting the Wells road, from which point the tourist travels for several miles over a successive continuation of inexhaustible coal mines that may, with truth, be termed the gold mines of England. From the Backwell Station, continued by embankment, in another mile, it reaches Chelvey, ¼ mile beyond which it passes Nailsea Court upon the right, and in a ¼ mile more, where it enters on a level course, carried forward in a direct line through alternate excavation and embankment, it arrives at The Yatton Station.
