The thing is the GEML has had extensive weekend engineering works, although predominantly on Sundays for the last 20 years near enough as I can recall during the FGE Days of having Sunday Engineering Works which continued through the NXEA days and now into the GA days, its as if the NR Engineering Works are being done so badly that there is always the case for them to happen throughout most weekends of the year, and generally of the last few years, most weekends there has been works south of Ingatestone mostly for "crossrail works" yet they have shown no sign of ending what with Crossrail years behind schedule, personally the GEML has suffered as a result of engineering works that personally shouldnt be so often as if NR, or Railtrack had done the works better in the first place, then they wouldnt need so many weekend possessions, and it does deter people from travelling on the line over the weekend especially if they live north of Ingatestone as they end up on a coach to Newbury Park and then onto the toxic central line for the rest of the journey into London rather than onboard an airy Class 321 or MK3 Loco Hauled train but with Crossrail several years behind schedule and no realistic opening time or conclusion of works, this is definitely going to have a major impact upon any GA Timetable as lets face it, Liverpool Streets TFL Rail platforms should have been freed for upgrade works by now as TFL Rail services should now be running into the tunnels from Stratford and not into P16-18 at LST as they still do, which is going to hamper GA doing any major changes to their timetable until these platforms have been released from Shenfield metro services.
