Pretty much all of the Limes 4850-4855 were bought in 1998 and started at Stanley, spent ten years there before being sent to Chester in March 2007 for the Lime. 4852 has had an accident, like 4854 although the latter was VOR for a LONG time a couple of years ago, and 4850 has been VOR a couple of times due to engine problems and pipe breaks etc (the worst B10BLE in the entire company if you ask me). 4853 spent a long period of time not out of service between February 2013 and May 2013, and if it was ever out in service I did not see it whatsoever.
