Wow, I've seen incredulous things posted on Sgf these few days,
but this tops the list. 
923M is de-registering on 12 Oct 2014, while the earliest of the
Citaros' deregistration only happens in 2028. So what are the
chances that BNDEP is that stupid to replace a Citaro from Sv 63
with 923M? I'll believe it if you're insinuating that the Citaro
out is replaced by a KUB of some sorts.
I see 0% chance that 923M's fate will be like 9573E's
reincarnation. And the week before (the last week of Aug), 923M was
still running around on Sv 9 & 17 etc.
Even if your brain can't come with a logical flow, use your butt
to think. What you had posted regarding 923M & Sv 63 just
defies common sense. If you're not sure, use the Suspected
Redeployments thread, that thread exists for a reason yeah? Come, I
clap for you. Well done.
Great! Nice comments from a sharp observer and even with your
superior knowledge, you need not put down people with 'use
your butt to think' insinuations...
Some bus fans in this forum have insider info, some talk to BCs,
others just do on road observations before posting
And thanks for the clap...
