I had spot similar bus design/bodywork in other countries from various sources..
The most common is SBS n its HK/UK counterparts.. like Dennis Trident, B10TL, LO, else..
For SMRT... not sure for its counterparts.. shld be various european buses like O405/G... Hispano bodywork..
For SMRT its always the modifield version with the doors changes to the left side as europeans drives on the right... hence door is on the right.
Any1 got more info?
I remember the old Leyland Atlanteans resembled those in Glasgow. Only difference was the latter only had one entance/exit.
