Oh dear, Goldenface, I seem to have made a major blunder.
I've looked up a bit and you are right.The carriages from Lime St. were hauled up to Edge Hill by steam driven winches; the return was by gravity, controlled by brakemen (sounds a bit dicey, that).
So no steam whistles, no smoke, no clanging.
What noises would there have been at Lime St. in 1847?
I'll have to rewrite that bit.
Thanks a lot. I feel pretty stupid, but better now than in the future.
Suppose I shouldn't feel too bad though, I've found a mistake in one of Ken Follett's books; but there again, to comfort oneself by pointing out the mistakes of others, is the comfort of fools.
Hope everyone has a really Happy Christmas. I hear you are all suffering with snow these days. Where I live, the sun is really hot today!
