February 2011 in Network Rail and Suppliers
Drivers are concerned about a defective semaphore signal in the Stow Park signal box area increasing the risk of a Signal Passed at Danger (SPAD).
The distant signal on the Up Line has been out of use since March 2010. The reporter believes a pneumatic/hydraulic component has been removed from the signal, meaning it is now always displaying caution. This could create complacency amongst Drivers, if the home signal is green they are now assuming the section signal will also be green and the distant signal is no longer referred to.
Network Rail would like to thank the reporter for bringing their concerns to our attention.
Could Network Rail comment on any plans in place to repair
the signal and explain why it has been out of use for
Stow Park 29 signal has been out of use for almost a year. Over ten years ago the signal was converted from mechanical wire operation to a unique hydraulic system due to the weight of the pull. When this unit failed after a long period of fault free service replacement parts were unobtainable as the company who made the kit had ceased trading. An alternative company has now been found and approved to carry out the repairs. At the end of February 2011 the unit was returned and fitted at Lincoln depot.
The long term plan is to convert both distant signals at Stow Park to standard parts to avoid a repeat of this situation.
