New intercity trains planned for NSW could come equipped with Wi-Fi and bike storage, NSW Transport Minister Andrew Constance has said.

The NSW government is spending $2.8 billion to create the new intercity fleet, which will link Sydney with areas such as the Blue Mountains, the South Coast, the Central Coast and Newcastle.

There will be 65 trains and 520 carriages in all, with the first due to be delivered by 2019 and the rest being delivered through to 2024.

Four groups have been invited to tender for the contract, which includes maintenance of the new fleet and the fit-out and operation of a maintenance facility.
