The current Northern plan is 2031 for a start of replacing the 150/155/156 fleets which given their size will take some time so the units have no option but to last into the early 2030's. The 150's, both Northern and GWR ones, are currently on an overhaul program which is costing big money and time due to corrosion. The corrosion issue is a reason why the TfW 150/2's are going to scrap as they become due overhaul, with parts recovered from them to support the other 150 fleets going then Northern and GWR should be OK.Can the units last that long? We hear on this forum that the 150's are "falling to bits". Is this members being overdramatic and actually they are perfectly capable of seeing another 6-8 years service- depending on when any new trains are ready. The 155s and 156s are also pretty old.
There seems to be a real contradiction on the forum, either the Sprinters, especially 150s are end of life meaning they have little chance of survival till 2031 or not. I struggle to know what comments I should take seriously and which posts are "for effect". Or does a massive overhaul answer all the problems?
If Northern get the TfW 158's then they could start a replacement of the 150/155/156 fleets earlier but on a very small scale so early 2030's it is for most of the units.
