Hello,
The Shore Line East thru trains which operate on the New Haven Line to Stamford do not appear on Radar or TrainTime. However, Radar and TrainTime do show the the arrival predictions (for Radar, on the countdown board) and (on Radar) the positions of non-thru SLE and Hartford Line trains. Thus, it appears that the Shore Line East thru trains are being filtered out of the dataset.
After consulting with an MNR engineer, he confirmed that it did appear on the "Virtual Train Tracking System".
Both of these screenshots were taken 2026-10-12 16:36~16:39 ET.
Thank you,
Ethan Charoenpitaks
