A train of aggregate hoppers from Acton to Theale threads its way through Reading station behind 66201. This would have started its journey on the relief lines but on the approach to Reading would have had to find a gap in trains on the faster main lines so that it can take the 'Berks and Hants' line to reach its destination. Reading Viaduct has just opened to carry trains on the main lines which are going towards Bristol; soon the track on the right will be run beneath the Berks & Hants line so that trains can run straight through the station on the relief line.
