Slowly, slowly. The removal of Rens from the Corridor, the dropping down to one HEP set, temporarily returned to two sets, sidelining of HEP cars, continued retirement of LRC cars are all part of a slow increase in the number of Corridor rotation lines covered by Ventures, now up to 16.
There are two impediments to more Ventures entering service. One is the ongoing CN-imposed reductions that continue to hamper Venture On-Time Performance. Couple this with ongoing court case in Quebec waiting to be heard as VIA seeks injunctions against CN restrictions.
Then there are ongoing maintenance issues that result from TMC servicing buildings not ready, niggling teething troubles with Venture maintenance (though VIA seems hesitant to release Venture serviceability data) one set never entering service and another in the shop after a September incident.
On the bright side, the incremental gains in Ventures that have entered service have resulted from all sets delivered, all operating crews trained, TMC and MMC staff knowing the Ventures better, finding mechanical and schedule workarounds, and limited creativity creating 32-axle sets. All of these have happened very slowly.
I have to imagine a world in which VIA orders these sets and is allowed to run them on some fantasy parallel Corridor free of any interference from the euphemistic 'infrastructure owner'. How different would that world be, and what VIA trains would be operating in it?
