The December 2025 Procurement Pipeline for Asset Management and Maintenance Services states that Metrolinx will be doing a pilot program with a diesel-battery hybrid loco starting with procurement in early 2027.

Are we sure they don't mean 12027? I'm not sure this can happen in less than 2 years, but I'll concede the possibility of 10,000 years...

Probably relevant article
It... is an interesting idea, though I'm generally not for it given the battery life. At the highest this means trains can run for 30 minutes at full load without catenary, otherwise the train is now running at half propulsion.
I wonder how they will work to tackle the short life of the battery. I have significant doubts that any line will have enough catenary to keep the battery charged by 2029.
Perhaps they will run this train on a 6 car consist, so even if the battery is dead the train still has good power.

this "pilot program" can be just that. A test. We are going to have enough gaps in the network that it could be useful in the future.

Isn't the 2nd engine for HEP?

Not an expert in locos so please take with a grain of salt, but from my research while some MPXpresses do use a separate engine for HEP, the MP54AC does not and diverts power from the prime movers

Thanks! My info was way out of date!

While not exactly related to the real equipment, i bet this would still be neat to some of you
I recently purchased these old paper trains I assume were made to promote the Metrolinx rebrand in 2013:

This is correct.
The MP54s are capable of operating on one or the other of the two prime movers - and in fact, they are designed to alternate between them in order to equalize their operating time - or both together. But as they don't have a separate motor for providing HEP, it thus has to come off of one of the two.
And because they use inverters rather than rotary devices to convert from AC to DC and back, they also don't have to worry about constantly running at full speed and syncing up with the 60hz required for the onboard power. Which means that they don't lose as much HP from their traction output, either.
