The shape of things to come ?

Here's a fairly rare event - a Cross-Country "Voyager" unit (number 221104) travelling as empty stock across the Sutton Park line on it's way from the Barton-under-Needwood (Wychnor) depot to Crewe, early this evening.
As far as is known, this is only about the fifth time such a train has used the Sutton Park freight lines.
Perhaps these units will be cascaded down to secondary services in the future, and form part of the fleet that will operate passenger services from Walsall to Birmingham via this route when stations are re-installed in who-knows-how-many years time ?
