    I was waiting at Springdale condo bus stop #43019 for service 173. At 1410 hr bus173 with registration number Xxx3002 zoomed past without stopping. Please take action on the driver. Thank you.

    One of your bus 173 was spewing tons of thick black smoke when I drove behind it along Humes into Hillview Ave ydy Sunday 15/04/18 around 1pm. I hope you folks at Tower will fix it before the LTA catches up and fine you. Very bad PR you know. The bus no is SMB 3012G

    I took a photo of the bus condition. If u want one, let me know and I will send to you.

    How does one knows which way the service is going (ie towards BT Batok or Clementi Interchange) if one waits at the bus stop opposite and before Jln Batu Nilam?
