How does a C4 exam take that long? Should be two or three weeks max.

What does a C4 exam cover?

What does a C4 exam cover?

C4 is the exterior of the train so bogies, couplers, under frame equipment and any other mods that might be required

A C4 overhaul is anything underneath the train. Bogies, cardan shafts (which connect wheels to gearbox to engine), reservoirs, valves.
A C5p is the paintwork, new livery or basic repaint into existing.
A C6 is the interior of the train, door systems overhaul, cab equipment (that's not covered as part of the C4 in some areas), seats, windows etc.

Those are bog standard exams on all fleets (except new build CAF/Stadler and so on).

C8, C10 are specifically Class 170 (and other variants, 165, 168 etc.) additional exams at different time periodicities.

156449 currently has a few extreme underframe corrosion issues so you won't see it until it goes to works at the end of this month (May).

Aren't these, along with the 150s riddled with corrosion? Would explain why it's taking so long.

Should be.
