As you know—we talked about this at our last appearance—we control when the train leaves the initial station. Afterwards, since our trains use infrastructure that doesn't belong to Via Rail, we have no control over the interaction with other trains and all the other events. As a result, we incur delays beyond our control.
We talk a great deal with the host railways, for both freight and commuter trains, to optimize the situation. The fact remains that we must deal with the infrastructure that our trains use.
