MML» and Hull trains cloned some.
And
LM▸ /Chiltern/LO are at the mo!
I think what Btline means is that Hull and MML used what were essentially Voyagers reconfigured and Chiltern uses 168s which are 170s designed to work with 16X units. LO are also goingto use an existing design modified for East and North london lines.
So a cloned 180 would be an Adelante with some of its deficiencies ironed out.
