The national government classified the subway as an Essential Public Service and required the company Metrovías to guarantee a minimum of service tomorrow, during the 24 hour strike decided upon by a group of delegates.

The decision was made by the Labour and Federal Planning ministers and the measure is to be implemented between tonight at 11 p.m. and all day tomorrow, and this minimum service would have to be approved by the National Transport Regulation Commission (CNRT).

In the meantime, spokespersons of the Labour Ministry said that all parts have once again been called to find a solution to the conflict.

On the other hand, Metrovías informed that it will dispose of "all the necessary means in order to guarantee a free service under an emergency schedule."
