Not necessarily.
The Operations & Maintenance contract has been voided, sure. But it had already been pushed back by 9 months, so it was pretty obvious that they were already in trouble.
But the Design & Construction part of the contract - which OnXpress has been working on for some time already - is still valid and in force. And they have been given a plan to work towards regarding track geometry and layouts to allow for electrification and enhanced service. They aren't going anywhere just yet.
