On 3 August 1863 a passenger train ran into a bullock near North Wootton station.
Five passengers were killed as a result with the poor state of the rolling stock being partially to blame.

On 26 September 1865 a light engine returning from Great Yarmouth to Ipswich derailed between Darsham and Halesworth killing the driver and fireman.

On 3 September 1881 there was a collision at Bow Road where a train ran into the back of a stationary train which had failed at the station.
The driver and fireman of the moving train were killed and 11 passengers injured.
In the inquiry that followed the cause was deemed to be the failure of the signalman to protect the rear of the train by placing signals to danger.
The train crew however were criticised in that while they had noticed the signals were not at danger, they had failed to inform the signalman.
The guard of the failed train was criticised for not having properly protected the rear of that train.

On 6 August 1889 there was an accident between Bishopsgate and Liverpool Street when an up passenger service ran into the back of a stationary empty coaching stock train.
The enquiry was unable to determine the exact cause of the accident due to conflicting witness statements.

On 25 September 1900 at Westerfield 0845, GER Class Y14 0-6-0 locomotive no 522 which was then just a year old stopped at a signal on the Ipswich side of the level crossing awaiting a route to the Felixstowe branch.
Shortly afterwards the boiler exploded killing driver John Barnard and his fireman William Macdonald, both based at Ipswich engine shed.
The boiler was thrown 40 yards (37 m) forwards, over the level crossing and ended up on the down platform.
Apparently the locomotive had a history of boiler problems although in the official report the Boiler Foreman at Ipswich Engine shed was blamed.
The victims were buried in Ipswich cemetery and both their gravestones have a likeness of a Y14 0-6-0 carved onto them.

On 5 April 1905 two trains collided on the junction directly north of Stratford Market station with the goods engine overturning and crushing its fireman William Secker.
