On 1 January 1927 there was a train crash at Woodbridge station. A wagon coupling had broken at Bealings station and when the engine stopped at Woodbridge, the rear portion running downhill smashed into the back of the stationary train. Only one minor injury was recorded. The line today runs north from Ipswich via Woodbridge, Melton, Wickham Market, Saxmundham, Darsham, Halesworth, Brampton, Beccles, Oulton Broad South; Lowestoft. It connects with the Great Eastern Main Line at Ipswich, the Felixstowe branch line at Westerfield, the line to Sizewell Power Station at Saxmundham, and the Norwich line at Lowestoft; the passenger service on the Norwich route is marketed as the Wherry Lines. Currently (2020) the line is double track from Ipswich to Woodbridge and then single to Saxmundham; from there it is double track as far as Halesworth, and then single again. There is a passing loop at Beccles, but the single line continues as far as Oulton Broad North Junction, where it joins the line from Norwich for the final entry to Lowestoft. The line is not electrified; it has a loading gauge of W10 between Ipswich and Westerfield and W6 for all other sections, and a maximum permissible speed of line of 55 mph.  Main line:   Framlingham branch:   Snape branch line:   Aldeburgh branch line:   Lowestoft and Beccles railway:   Haddiscoe to Lowestoft link (via the Lowestoft Railway):   Haddiscoe connection:   Greater Anglia passenger services are operated by Class 755 "FLIRT". Freight to Sizewell on the former Aldeburgh branch line is typically in the hands of Class 37 or Class 20s whilst Class 66 and Class 70s work trains to Felixstowe. The following is a list of signal boxes operational during the steam and early years of the diesel era. They are listed south to north. Two of the stations on the line had level crossings incorporated into the platforms. At Saxmundham the original down platform (the platforms here were staggered rather than opposite each other) required extension for longer trains and rather than close the Chantry Road, the platform acted as a gate and were swung across the railway when road access was required. A train hit the road gate in the early 1960s and the platform was replaced by more conventional gates.
