In 1846, the Manchester and Bolton Railway (whose line the ELR used to gain access to Manchester) was taken over by the Manchester and Leeds Railway, which, the following year, became part of the Lancashire and Yorkshire Railway (L&YR). The ELR's expansion and the opening of new routes—including an alternative route between Manchester and Leeds—had caused a degree of consternation at the L&YR, but the two companies initially managed to work together successfully. After about three years a dispute flared up over the collection of tolls for the ELR's use of the line. The ELR had become accustomed to running their trains on to the L&YR line and then later declaring of the number of passengers liable for a toll but, in March 1849, the L&YR insisted that ELR trains stop at Clifton so that passenger numbers and tickets could be checked by their own employees. The ELR accused the L&YR of trying to impede their traffic, particularly as they had recently gained a connection to Bradford, in competition with the L&YR. They stated that the L&YR had access to their accounts, and to the returns made by their staff. On the morning of 12 March 1849, despite the presence of police from Bury and Pendleton, the L&YR placed a large baulk of timber across the ELR's line at Clifton Junction, effectively blocking it. Employees from both companies arrived at the scene, and a large crowd gathered to watch events unfold. The L&YR also pulled a train past the junction, blocking the up line to the city. Its engine was pointed south-east toward Manchester, available to any ELR passengers who wished to continue their journey. An ELR train arrived from Bury, and stopped. L&YR employees attempted to take tickets from the ELR's passengers, but were refused, as the ELR had already taken tickets at their Ringley Road station. ELR employees then removed the baulk of timber, and in an effort to push the L&YR train out of the way, drove their train forward. The L&YR had anticipated this, and moved another engine (taken from a L&YR train from Manchester) to the front of their Manchester-bound train. The ELR then blocked the L&YR down line with another of their trains, laden with stone, moving it to a position directly abreast of the L&YR train. The line remained completely blocked until about mid-day, with a queue of trains from both companies, and
