NR maintenance teams are on continuous standby to deal with broken rails and do so in a timely fashion. However,when a train derails and continues for some distance causing continuous damage the permanent way it will take considerably longer (2 miles quoted on the NR Anglia
website). The few pictures above infer the housings on at least one rail have been sheared off and if its continuous even the use of tie bars with a Temporary Speed Restriction may not a short term palliative to get the line open as it will need resleepering and probably the resources to do that are tied up Maryland this weekend. One would have thought they would be mobilised next week as the line is shut and i would have expected reseleepering even two miles can be done in under a week. However, another observer suggest there are overbridges along this stretch and its entirely plausible that damage has occurred to the wheeltimbers or bridge structure which may have a longer lead time for bespoke components rather than sleepers off a stockpile.
