When you stand on Platform 4 of Warrington Bank Quay station there is a very distinct smell of soap, probably washing powder. It is not surprising given the large Unilever factory right next to the station. A quick google search shows that they do indeed make detergents there – it’s a relief to know isn’t an olfactory trick!
