What types of cars face a speed restriction of 25 MPH under high wind warning conditions?

Empty bulkhead cars or double stack intermodal cars face a speed restriction of 25 MPH under high wind warning conditions due to their specific design and potential for increased susceptibility to high winds. These types of cars can present more aerodynamic profiles that catch the wind, making them less stable during windy conditions.

The restriction is put in place to ensure safety on the tracks, as the risk of derailment or tipping increases with the impact of high winds on these lighter cargo types. As a result, their operational speed must be reduced to minimize the hazards associated with high winds, ensuring the stability and control of the train while navigating through affected areas.
