Estimates Committee B - Answers to Questions Fifty-Second Parliament, Second Session (52-2) 52 2 Parliament of South Australia Estimates Committee B - Answers to Questions published Estimates Replies O-Bahn O-BAHN In reply to Ms CHAPMAN Legislative Council Deputy Leader of the Opposition O-BAHN In reply to Ms CHAPMAN (Bragg—Deputy Leader of the Opposition) (27 June 2013). The Hon. C.C. FOX Legislative Council Minister for Transport Services Minister Assisting the Minister for the Arts O-BAHN The Hon. C.C. FOX (Bright—Minister for Transport Services, Minister Assisting the Minister for the Arts): I have been advised of the following: There is no track realignment currently occurring. The O-Bahn track is supported on piles embedded in the ground. A smooth riding surface is maintained by jacking up the track to its original design level and filling the gap between the top of the piles and underside of the track with high strength mortar grout. Maintenance work involving track levelling to address a gradual settlement of the piles resulting in an uneven ride at a location approximately 1.77 kilometres from Park Terrace has been scheduled for the next programmed weekend closure for track inspection and maintenance on 26 and 27 October 2013. A 60km/h speed limit has been in place over a short section since May 2013. The track levelling will improve ride quality for commuters and, once completed, the speed limit will be removed. The estimated cost for this work is $25,000. Funding will be from the O-Bahn track maintenance budget that is already allocated for the 2013-14 financial year. No further funding will be required.
