Tri Rail (Florida) Locomotives

[Iskra]

It is my understanding that this line on the East Coast of Florida runs with a mixture of locomotives. Some are new build Brookville BL36PH locomotives and a minority are older but rebuilt PPLX M-K F40PHM-3C locomotives that look like more traditional old US locomotives. My question is thus; on a given day is there anyway to tell which services are run by which locomotives (ie is there an online tracker that tells you, or do they stick to a certain area), or do you just have to see what turns up on the day?

Thanks in Advance

Some searching turned up an official Tri Rail tracker, at http://trirailpublic.etaspot.net/
Unfortunately, for each train, this only shows the train number and expected times at the next few stations - there's no information on train composition (which is where I'd expect to find the loco number). There are quite a few other US trackers available, but those I know either don't include Tri Rail, or don't provide any more information than the official tracker.

Tri Rail only has two routes: the long-standing Miami Airport - Mangonia Park route, on which all trains run the full length, and a shuttle between Metrorail Transfer and Brightline's Miami Central station opened in January this year. I would guess that the two types are used on both routes, effectively as a common pool. I suspect a US-based forum might have better information - RailroadForums (https://railroadforums.com/forum/index.php) might be one to try.
