Is their MTA data more reliable than Google's? Terribly often, and especially on week-ends, Google Maps will tell me a subway is coming even when the line is closed, rerouted, etc. I understand taking all temporary changes into account is a hard problem, yet I can't help finding it ironic that in the city which hosts their second largest engineering center, Google can't get that right.
Can't speak for MTA but in London the Citymapper service updates are pretty great. It tells you what's closed, notes disruptions when showing trip suggestions, and you can preview upcoming weekend's disruptions. About the only problem is it shows the disruption icon on trips that use the non-disrupted part of a line.
