Illawarra rail commuters who spend an hour on the train to Sydney need a dedicated transport plan for when they return to work, according to local Labor MPs.
On Monday Transport Minister Andrew Constance said the government would be retaining social distancing measures on the network's trains.

That would be achieved by cutting capacity by 75 per cent, which equated to 32 people per train.
Keira MP Ryan Park said the changes caused problems for the region's commuter population.
"It takes commuters in the Illawarra and the South Coast an over an hour to get into Sydney, on trains that are regularly overcapacity already," Mr Park said.
"These changes mean that some people won't be able to get on their regular trains if there isn't enough space, leaving them waiting to see if they can fit on the next train.
"The Berejiklian government must release a clear public transport strategy for people in the Illawarra and on the South Coast."
Wollongong MP Paul Scully branded the plan a "one size fits all approach".
"It appears Illawarra commuters and their employers have been the last to be considered in this transport plan," Mr Scully said.
"It could be greatly improved by working with employers to stagger start and finish times; setting up satellite offices in large centres like Wollongong and the provision of additional services both in Wollongong and between Wollongong and Sydney."
In an effort to reduce the numbers of people on peak-hour services, the government has encouraged workers and employers to consider staggering starts and also to continue working from home practices if suitable.
