PASSENGERS have expressed frustration over Sydney trains after delays have caused customers to spend hours stuck, causing huge delays to the already troubled network.
Some services were delayed by up to one hour due to urgent repairs to the overhead wire at Wynyard in the CBD of the city last night.
Although the situation was so confusing for some commuters, the passengers at the Lidcombe station reported that the driver simply "did not arrive".
Sydney Trains tweeted that the services between Wynyard and Central have been suspended in both directions because of the work, and the website says that various services have been affected.
It also warned that indicator boards, real-time apps and information about train journeys may not be available or incorrect.
Commuters have been told "Delay non-essential trips or use local buses where possible".
On Twitter, Trans Info has posted several tweets to warn commuters about the importance they can experience if they plan to use the train service.
Several commuters have also expressed disappointment on Twitter about the lack of an announcement of delays to their customers.
Channel 7 also placed images of passengers evacuated from the trains at Wynyard last night.
The interruptions are probably uncomfortable for hundreds of Sydney sports spectators preparing for their way to the Olympic Park, Randwick and the Flawless Stadium to watch a variety of sporting events.
Among those events were the long-awaited race with champion mare Winx on Royal Randwick and Sydney Swans who took the Greater Western Sydney Giants in the Olympic Park and the Bledisloe Cup at the ANZ Stadium on Saturday night.
Meanwhile, Shadow Transport, Minister Jodi McKay told the Daily Telegraph the assignment to transport minister Andrew Constance to "assure commuters that trains to normal ti Sunday afternoon are accessible with major sporting events."
"Rail passengers have reported today that not only trains do not run on time, but there is a serious lack of information about the cause of delays, "McKay said in a statement accompanying the publication.
"Thousands of spectators are expected to use public transportation this afternoon and evening to attend the Bledisloe Cup and AFL and NRL competitions in the city."
A spokesman for the Sydney train told news.com.au: "Train services for the entire Sydney Trains network are affected by an IT problem at all transport companies.
" This has affected key operating systems that increase the visibility of trains and their locations. Technicians are working to solve the IT problem with systems that will be operational again via the transport network.
