150202 is a strange refurbed beast, play spot the peculiarities.
Essentially a 150/2 but with 150/1 3+2 seating with sections of fixed longitudinal seating by the bike spaces and toilet; there is a divider between the wheelchair space and the toilet plus a longitudinal seat sandwiched between the two; it has 2 emergency cupboards; the ramp is stowed in a cupboard facing an intermediate vestibule; the ceiling is lower in a lot of places; there a no tables; and the PIS is located in slightly different places (this is another difference - the PIS announces the next station upon departure of the previous, but not on the approach, and it can't handle request stops ie any door activation causes it to skip to the next +1 non request stop).
