The MBTA announced Thursday it will launch a renewed effort to collect subway fares with written warnings and fines of up to $150 early next month.

Faced with a massive budget deficit, the MBTA is set to deploy fare engagement representatives to issue formal warnings and citations to riders who have not tapped at a fare gate or farebox,

In a social media campaign launched Thursday, MBTA General Manager Phillip Eng emphasized the importance of fare payment, stating that it is crucial for maintaining and improving transit services.
