The short answer to the question is no. The JSON feed does have a new “track” field in StopTimeUpdate (that’s non-standard/non-complaint with the GTFS-RT specification…)
that was added a couple of weeks ago.
However, the like the rest of the information on the LIRR’s GTFS-RT feed, it’s all past tense. The track information is only communicated with the rest of the StopTimeUpdate field, which is only done as a train is “timed” at that location (i.e. it is arriving
or departing a station). That means if you’re looking for what track a certain train will arrive on at Mineola, for example, the GTFS-RT StopTimeUpdate field will only update for Mineola when the train is actually pulling into Mineola station. And that’s
if the feed updates at Mineola at all, which can’t be relied upon at any particular station or at any particular time.
Then by time you pull the feed and pass the information onto your users, the train is either sitting in the station or has already left. So the information as it’s conveyed now in the LIRR’s GTFS-RT feed is basically useless. At stations like Atlantic Terminal
and several east end terminals where the feed only updates after the train has departed, you wouldn’t get the track number until the has already left the station.
If you’re looking for what track the train will arrive on before it actually gets to the station (which I assume would be the case for most applications), there’s no way to get that from the GTFS-RT feed now. The only way you could get that information
is through the Departures feed of the TrainTime API. However the trouble with that course is the feed is only available station-by-station, so you would have to pull the feeds for 120-something stations individually to get the full picture.
The situation has not really changed since it was first brought to the MTA’s attention
through this this group almost two years ago in April 2016. At the time I suggested the railroad put out some sort of Alternative Status Feed through the TrainTime API that would consolidate all of the information already conveyed through the various TrainTime
API feeds onto one feed so developers can pull 1 feed (instead of 124) and get the complete picture of what’s going on in a way that’s not possible with the way the LIRR’s GTFS-RT feed is currently set up now.
There was no response or resolution to that issue at the time, and the issue still persists years later. Knowing what track the train will arrive on (before it actually gets to the station) is very valuable to riders, it would be good if the LIRR could finally
figure out a way to make this information available to riders in an accurate and reliable manner.

Yes, the LIRR GTFS-RT feed has track information in it. Try hitting the json endpoint.

Where do you want this data? Are we talking scheduled tracks in GTFS or realtime tracks in GTFS-RT?
