6166S debuted 403 last time ._.
uh dude, I think he (SMB228X) was referring to the debut of
Citaro cameos on 40 & CT18. Not 403. I think you replied to the
wrong post. 
Besides, 403 has been getting Citaros every week. It's happening
like once every 3 days on average. It's a common sight, just that
the permers 8215X 8333M come back to 403 everytime. Same for 8419A
which just loves to do Sv 109 recently but comes back to 354 the
day after.
Anyway, 6183S on Sv 403 for 05 Jun as well. Replacing 8215X.
Didn't catch what replaced 6183S's timings on Sv 6 though.
