MIDLAND, Texas (AP) -

Federal investigators plan to re-enact the factors that converged in a West Texas train crash into a parade float that killed four veterans.

The National Transportation Safety Board has scheduled the test for Tuesday afternoon at the Union Pacific railroad crossing in western Midland where the crash happened.

One person remains hospitalized in Midland with injuries from last week's crash of a freight train into a veterans' parade float.

Midland city spokesman Ryan Stout says Midland Memorial Hospital had transferred to a critically injured patient to a hometown hospital after the patient's condition was stabilized. Hospital spokeswoman Marcy Madrid says she doesn't know where the patient was transferred.

Madrid says that leaves one patient in stable condition at the hospital who will eventually also be transferred to a hometown hospital.
