Methods, systems, and apparatus for obtaining solutions to train and driver recovery problems using quantum computation. In one aspect, a method includes receiving data representing a train and driver recovery problem, wherein the train and driver recovery problem comprises a task of recovering from a disruption to a planned train and driver schedule; generating, based on the data representing the train and driver recovery problem, a quadratic unconstrained binary optimization (QUBO) formulation of the train and driver recovery problem, wherein the QUBO formulation excludes variables that relax constraints on driver duties; obtaining data representing a solution to the train and driver recovery problem from a quantum computing resource, wherein the data representing the solution to the train and driver recovery problem comprises an adjusted train and driver schedule; and initiating an action based on the obtained data representing a solution to the train and driver recovery problem.
