According to news items reported by the
Fen Line Users Association, each time anyone opens their mouth the cost of sorting out the level crossings north of Ely keeps escalating (the local MP has now stated that all the necessary upgrade works are now costed at north of £100M). Some say, including someone I spoke to who works on that stretch, that this is a way of kicking the proposed upgrade into extremely long grass.
To summarise more succinctly, he told me ithe upgrade was was never going to happen and that Lynn would have to be happy with the current hourly service. Which, in my opinion, would make an upgrade to the KGX - Ely service unlikely.
Interestingly, the sky-high costs now being quoted have created kickback from some West Norfolk residents, who would prefer that such a large sum is invested in road improvements instead.
