I'm well out of touch on this, given I haven't travelled on 378s since introduction.... When was the relivery work moved from Ilford to Widnes? I remember 135, 150, 147, 136, 232, 204(?) being done at Ilford
The first 378 arrived in Widnes mid January. Despite some going to Ilford first, all 57 units will go for repaint at Widnes
