NTfL (New Tube for London) has not been called that for a while now, it’s Deep Tube Upgrade Project. The only trains on order are for the Piccadilly. With potential follow on orders for Bakerloo, Waterloo & City and Central lines in that priority order.People have commented about the significant reuse of old parts being drab, I'd assume this is to cut costs given 92 stock are next in line for replacement under NTfL. Yes, I know Bakerloo stock is older and is in more need, however my understanding is TfL are prioritising Central for replacement first due to the higher usage rates (even after considering usage reductions from XR)
They’ve decided to do a major refurb on the 92ts instead, new traction packages, train management systems, lighting, LED screens etc which will see them going for quite a few more years yet.
Although it has been said that they can’t afford new trains for the Bakerloo until the extension has been built.
There were also fresh talks (in 2021 ish) of buying a new fleet of trains for the Jubilee as they could do with a few more, then send some 96s to the Bakerloo to replace all the 72s and the rest to the Northern to supplement the similar 95s.
