We arrived at CST station about half an hour before departure. The boards at the entrance clearly displayed train number, name and platform. Platform 17 is to the furthest side and a bit hard to locate. The station of course smells a bit of fish as expected, but it is not too bad.
Since two of the tickets had been originally wait listed, the charts at the head of the platform displayed confirmed status and the coach number for those. We already had this information though.
We roll our suitcases over broken concrete, around baskets and cleaning machines, past the luggage coach smelling strongly of fish, but it is being disinfected.
