Rename of the alternative route parent route

Just a note, some of the SBS Transit alternative bus services like 98A, 162#, 163A will all use the suffix M instead. For 98A and 162#, they will start from 28th January 2008. They may still be other alternative bus services which will be renamed too which I couldn't confirm yet as of now.

In my opinion, it is a bad idea to use M as a suffix. Last time, before the Nite owls the Ns come out (1N to 8N), the previous Nite Owls services contain Ms as the suffix. 162M is used by SBS Transit not long ago as a Nite Owl service. Besides, it doesn't make any difference by renaming it for services which already have a suffix behind it like for example 98A and 163A. Commuters differentiate the different bus services simply just by seeing whether the service has a suffix behind the parent bus service.

Just a thought.
