The Yorkshire Post says: Carillion, HS2 and Leeds - what next?Train cleaners have been told to work normally, but their fuel cards are not working, according to the Rail, Maritime and Transport union.
One cleaner filled up at a petrol station, but the Carillion Fuel Card bounced.
The RMT said it was the start of the "brutal reality" facing Carillion workers.
The stricken company employs 20,000 workers across Britain and hundreds in both Sheffield and Leeds.
Workers arriving at Carillion's corporate head office in Wolverhampton were reluctant to speak to reporters as they entered the building near the city's ring road.
The Black Country Chamber of Commerce described news of the firm's slide into liquidation as "incredibly sad" for the local area and the country.
Speaking outside Carillion House, at the junction of Salop Street and Fold Street, the chamber's chief executive, Corin Crane, said: "I don't think anybody woke up this morning expecting liquidation so it's been a real shock for us.
"What we hoped for was administration and some more time to work through some of these problems and to give security to the workers behind us.
"It's an incredibly big business and it's been very successful over the years."
Yorkshire workers await news as Carillion collapses into liquidation after crunch talks failPledging to support the 450 staff based in Wolverhampton and at smaller local businesses undertaking work for Carillion, Mr Crane added: "Real immediate things need to happen and the first thing is reassurance around some of these contracts.
"There will be contractors all over the country waking up this morning not sure if they have got work at the end of the week.
"We need to know what will happen with those really big contracts."
Asked what had gone wrong at the construction and support services giant, Mr Crane said: "What we do know now is that there was something wrong with the balance sheet.
"An awful lot of work has been awarded to Carillion, knowing that there have been some problems with their finances for some time.
"I think those details will come out in the coming days.
"This is a really old company, it's been in the Black Country for over 100 years. It's the very fabric of our local construction industry so it's an incredibly sad day."
