File:Sydney Metro Northwest – Castle Hill Community Open Day

Description
More than 700 people got a look behind the green fence at Sydney Metro Northwest’s Castle Hill community open day in October 2015. Special guest was Tunnel Boring Machine 2 Florence, with all 120m of this mega machine on show as she took in the rays at the bottom of a 25m excavated box where the platforms of the future Castle Hill station will be. Thanks for joining us at Castle Hill.
