And maybe also the WA MBO405s that are due for scrapping soon...
really going to miss those AMDEP buses they rock. 
Maybe next time we'd see Scanias on 53, 54, 55, 56, 58, 59 and 410.
Think these Bishan bus services used around (or close to, not
really able to estimate) 30 ~ 40 of those WA MBO405s.
