A new freight rail route by CSX will commence on Tuesday to bypass the Port of Baltimore's closure.

• The new route for diverted Baltimore imports arriving at the Port of New York and New Jersey begins on Tuesday, as announced by CSX to CNBC.
• The rail freight intended for the Port of Baltimore will now be redirected to the Port of New York and New Jersey.
• The port may remain closed for several weeks due to the bridge collapse, resulting in cargo congestion.

On Tuesday, CSX will launch a new dedicated freight rail service between Baltimore and New York to assist its clients in overcoming the trade disruption caused by the collapse of the Francis Scott Key Bridge after a cargo vessel named Dali collided with it on March 26, leading to the closure of the Port of Baltimore.

The Port of Baltimore-bound rail freight that was previously diverted to the Port of New York and New Jersey will utilize a new CSX service, according to the freight railroad. Additionally, freight destined for the Port of Baltimore as exports will also use this new service to reach the Port of New York. The amount of freight being transported on the new line is currently undisclosed, as CSX is in an earnings quiet period.

The railroad uses its international sales network to transport freight between New York and Baltimore through strategic partnerships with steamship lines.

The new service will aid in managing the traffic flow that usually passes through the Port of Baltimore, according to a statement from a CSX spokeswoman to CNBC. However, she emphasized that the situation at the port is constantly changing. Although the timeline for resuming freight operations at the Port of Baltimore is uncertain, CSX is in continuous contact with its customers, providing prompt updates on the status of their shipments. CSX is fully committed to fulfilling its customers' transportation requirements during this challenging time.

Last week, MSC informed its shipping clients that passage to and from Baltimore is currently impossible and will not be restored for several weeks or even months.

Diversion ports will be responsible for transportation arrangements once cargo is delivered.

There are 10 vessels at the Port of Baltimore, excluding the Dali, which are stuck and may require alternative freight options, including rail.

"Aaron Roth, retired Coast Guard captain and Chertoff Group principal, stated that the system is currently adjusting and will take some time to complete, as the magnitude of the event is still being assessed."
