There was another railway line, built in 1866, which linked the above London & North Western Railway branch line to St Albans, to the newly constructed Midland Main Line from Bedford to St Pancras at Napsbury. It was a goods line in brief use, closed by 1910, called the Park Street Branch and was operated by the Midland Railway. The railway bridge near Sycamore Drive was demolished around 1948 after being damaged by a giant propellor being delivered to the Handley Page aircraft works.
