S1 returned to Metrobus a few days ago and is back to using its old allocation. Which sounds weird to say because S1 used these buses before. Luckily the limpy AL E200s/Esteems (namely the Enviro SN12s) are no longer on this route. This driver was good and there was lots of fast moments and this bus is quite a nippy bus. Also this route is nice
