Answer:
Why has the provider of choice shifted from rail to motor modes?
When companies change their modus operandi, it is usually to minimize cost and maximize profit. This provider of choice therefore has probably determined that motor modes were more cost effective for the services it offers vs using trains and rail modes for transport and has now made the appropriate switch.
With the shift to motor freight carriers, the amount of traffic accidents have sky rocketed.
With the provider of choice now using motor modes as opposed to rail, there is bound to be more vehicles on the road now from motor bikes all the way to trucks and with an increase in the number of vehicles available, there is bound to be an increase in accidents involving vehicles.
