L423 (51361, 59513 & 51399) passes Oxford North Junction on 7 April 1990 with the first up local train of the day - the 2C15 07:54 Banbury to Oxford Network SouthEast service. Work had just started on the left, clearing years worth of willow trees and other bushes from the course of the former down relief line. This revealed a large hoard of Victorian bottles and jars, presumably from the site of a former rubbish dump.
