if bus breaksdown for tat day, at least can cover say maintenance
shortage of buses.
But if ppl were to know tat's it's replaced w/o notice, it
becomes a committment issue. I committ something to e
community but it's not done.
so now also no one mention what is the replacement bus...
further, 2 of Sv143 LO3x were kicked out and 7530 was deployed
recently on Sv143 . i think another wright (7529 or 7537) might be
deployed as well. so in the end, there isnt any reduction of WAB on
Sv143 as well. Maybe you did not realise at all....
There might be some internal switching of slots though...
