Ravensthorpe itself was something of a 'new town' in it's day (it was originally called Newtown) and sprang up quite quickly after the textile boom turned the area from being primarily known for mining and agriculture to woollens. As a result it's station on the main line was a relatively late addition 42 years after the line; there wasn't even a road, let alone a bridge over the Calder.
The L&Y already had a station just 3/4 of a mile away at Thornhill, and not much further away was their own Ravensthorpe station on the Spen Valley line, which wasn't much more remote from the centre of Ravensthorpe than the LNW one, which is still a bit on the remote side really.
