Commuters who take the MARC Train can likely expect reduced service Wednesday morning.
The Maryland Transit Administration said Tuesday trains could be delayed because there are not enough train engineers and conductors to work.
Tuesday's earthquake caused severe delays on the Penn, Brunswick and Camden lines. Service was temporarily halted and then operated at reduced speeds once service resumed, meaning long hours for the workers.
The Federal Railroad Administration requires train engineers and conductors receive a minimum rest period between work shifts. There are standby employees to cover such situations, but there are not enough replacement crews to cover all trains.
MTA said should have a decision by midnight if and what trains will be delayed.
