"Again, I want to stress this is a big project with big 

problems," Ms Berejiklian told reporters in Sydney on

Friday.
"We're relieved the first one is on the track but there is still 

a long way to go."
Downer EDI, which has the contract to construct the

Waratah trains, said they would be the backbone of the

Sydney rail network for many years.
"We look forward to delivering the remaining program over

the next three years," Downer CEO Grant Fenn said in a

statement on Friday.
The government's contract with Downer provides for 626 

Waratah carriages (enough for 72 eight-car trains) to be

delivered at a cost of $3.6 billion.
In 2006, then transport minister John Watkins said the first

carriages would be in service as early as 2008, with all

carriages in service by 2010.
Premier Barry O'Farrell joined Ms Berejiklian at the Friday

press conference and confirmed that there were no plans

to privatise City Rail.
His comment comes a day after Infrastructure NSW chief 

executive Paul Broad said privatising commuter rail had

worked well in Victoria and could be an opportunity for 

NSW.
Asked on Friday if the state government would consider

such a plan, Mr O'Farrell said, "No."
