The Hook Continental ceased immediately at the outbreak of
World War II and the three ships operating the ferry sailings were requisitioned for war service. The train service officially restarted in November 1945 using the same coaches and locomotives as pre-war, but with only three sailings per week. Of the three vessels that had been used pre-war, the was lost and the was purchased by the government as a troop carrier leaving the as the sole vessel to operate the service. The train was restored as a daily service in the summer of 1947 with the arrival of the faster and more capacious vessel "Arnhem" from the
John Brown Shipyard on
Clydebank. The
Thompson B1 class 4-6-0s took over the duties at that time from the
B17s and continued as the principal locomotive on the train until the advent of the Britannia pacifics after which they were still used for relief services until the withdrawal of steam haulage in the Great Eastern area in 1962. At this time the train weight had grown to 485 tons tare/520 tons gross and the allowed time was actually increased to 90 minutes compared to the 82 minutes of 1912. With the introduction of
train reporting codes, the Hook Continental was considered a Class 1 train (express passenger) and the route between Liverpool Street and Harwich was assigned the letter F giving a headcode in the format 1Fnn. Even numbers indicated down trains and odd numbers up trains.
Relief trains During peak traffic periods in the summers of the mid-1950s, particularly on a Friday night, there would be an additional ferry sailing, requiring several relief trains, these usually being hauled by
Thompson B1 class. During the summer of 1957 there was a second train, with third-class only accommodation, which was scheduled to run 10 minutes after the main train, and with three further reliefs available as required. Only one of these reliefs would stop at an intermediate station,
Colchester, and only the main train was advertised in the timetable. In 1980 there was a separate train shown in the working timetable but not shown in the public timetable running 20 minutes behind the second of the two published trains.
Day Continental The LNER introduced a balancing working to the
Hook Continental called the
Day Continental which left Liverpool Street in the morning and returned from Harwich in the evening. The last scheduled steam-hauled passenger train to arrive in Liverpool Street was the up Day Continental on 9 September 1962 hauled by a
B1 class locomotive and the use of the name
Day Continental for a working from Liverpool Street to Harwich in the morning with a return working in the evening continued into the BR diesel era with the timings in 1984 being the exact mirror of those for the
Hook Continental. In 1980 the Day Continental was shown as running "as required". ==BR Diesel days==
