Some of the DDU showing the bus number details of particular bus
stops..like what other buses are there at that bus stop.. however,
at each stops sure got miss out a few service.. so i dun know why
they will provide inaccurate info
eg: At bus stop 44129 (Opp Blk 113), SG5752T DDU shows 188,188E
and 188R, but when reach next stop (44449 Opp Blks 237/239), it
only shows 982E and NR3...
Spotted on SG5041L and SG5752T
SMB121U has this feature on DDU also.. even shows premium svcs
like 555
