Travelling along Tom Benson Way, the road that occupies part of the former 4-track Fylde lines approaching Preston, I noticed a series of posts supporting steel baffles (is that the right word? if not, what is?) alongside the up Fylde line near the junction of Tom Benson Way and Fylde Road. Am I correct in assuming that these are designed to prevent drivers seeing the traffic lights at the adjacent road junction and mistaking them for rail signals in the dark? Are there any other places on the network where similar measures are needed?
