Well one or two new house-holders might be a bit grumpy and there is the little problem that the new line would have to be routed away from where the level crossing was because that would never be sanctioned now.
If you carry on beyond Earby it sometimes becomes more of a cutting than an embankmnt and becomes seriously wet but I think I have been as far as Foulridge. I am not sure how far you can get towards Colne.
