Australia's New South Wales Rail Tram and Bus Union (RTBU) has criticised investment in the northwest rail link as being too little too late.
NSW RTBU secretary Alex Claassens said work should start in January 2011 instead of making Sydney's commuters wait 14 years, according to The Sydney Morning Herald.
The A$50bn Metropolitan Transport Plan officially scraps the CBD Metro with the work now due to get underway in 2017, ten years after it was announced, and be completed by 2024.
Experts are now pointing to a $4bn black hole in the project, which has no provisions for extra capacity crossing Sydney Harbour.
Claassens said the union put forward three shovel-ready projects for the northwest link in June 2009 and was surprised work would not start for another seven years.
The union believed money would be diverted from the CBD Metro and say if the money is there, as it clearly is, it should be used for the new line.
Claassens said public transport workers would like nothing better than a system they could be proud of.
