Tambun

This set of shophouses would be all there is about the tiny Tambun town which estimated of being not more than 500meters a stretch.
I wonder what significance there is for such small township to exist back in the colonial days. I have been passing through this town my entire teenage days, and these days the town has shown its signs of 'exhaustion'. If there is some interesting story behind the town, it'll be worth to dig up the history of Tambun! (So, add on to my 'cart' for ongoing task)
