5073S bunched with 1241Y, and 5899B bunched with a
citaro..
Bunching is getting more common after adding the DDs..
The issue is more with the # buses. When you operate with 19
buses, it is designed to bunch as frequency is 02-03
mins.
Likewise for 911. Even if have no DDs, spotting 3-4 buses bunch
is common everyday.
Hence need to reduce number of buses and create appropriate
spacing when you add high capacity buses, otherwise it is waste of
resources.
