The Newton Heath fleets (150/1, 150/2, 156) have been covering for months/years for the 769 fleet whose availability has been dire. The availabilty (booked 6 out of 8, now 10 with the 2 ex TfW units, one of which still to appear, the other that has worked 2 days and failed in service both times) has varied between 0 and 6, but generally 3-5 which means that unless short-formed NH has to supply aanything from 6-10 DMU's additional. From December there are more EMU workings utilising the newly electrified Wigan to Bolton line with a new EMU service from Stalybridge to Wigan North Western, together with the fact that the 8 Northern 769's 'should' have been to Brodies for overhaul but their reliability on return has been shall we say 'hit and miss'.They work so well that Northern are reducing their availability by 5 from December...
Back on topic, the 3 units sent to BY were all longstanding NH units, no different to any other of the 150/1's but they have been worked hard for many years. If they are so bad, we'll have them back, even with allegedly dirty seats - from the photos shown though, they don't look so bad.
