When I saw these buses it was about 2.00pm, I saw the nifty 50 leave town pretty full which was very busy, on 31479 there was about 6-8 people and the cadet was empty so that's strange that they've been running around together for a while as it's a bit pointless and are there 5 buses that operate on the 50 in the day? I wonder what happened to the other nifty 50 buses, were they being used on other routes?
