From what I know so far about the replacements & others
which should be true:
983P, 1964M, 1966H
& 1982K: Unknown?
975M 1971S: Highly likely 6601C 6602A 6603Y
from my spottings. Can someone check if 970B is still on?
986G: Replacement is another Mk4 (based on my
spotting of 17/17A timings).
987D: Should be one of the
SP E5 KUBs (8641Z? I'll KIV this)
1963R: Seems like 6641L with the ad?
1969A: 2627E (ex-196/196e)
1972P: 8667A? (to be KIV)
1973L, 1975G & 1976D: 2762Y 2765P 2768G?
(according to Wiki)
1974J: No fixed replacement after close to 3
weeks. Always random Citaros.
1979X: 956T? (ex-14/14e)
1984E: 2597H (ex-196/196e) with the ad.
983P is replaced by 6795/6796. Will see the bus on 401 to
know.
1964M is 6677P. There is another citaro 6800U going on 9 and 35
often.
1966H is either 6685 or another 669x bus
1979X is 956T more or less. Its on it 2 weeks now.
