Problem

The map has no rail right-of-way, stations, portals or bridges; the only transit concept is the 511 transitOperations glyph, which rides the dead 511NY feed (#198).

Who asked

RCC, GSOC, OEM, TOC, HOBBY (5 of 8).

Proposal

Phase 1: MTA GTFS static shapes + stations (MNR, LIRR, subway, bus) as a layer; GTFS-rt service alerts drawn on affected lines/stations.
Phase 2: distance from each incident to nearest ROW segment/station stored and shown as a rail-card chip ('85 m from Harlem Line ROW'); feeds the watch-zone issue.
Vehicle positions / ETA-to-milepost: LATER.

Data source and terms

MTA developer feeds (free key). MTA Data Feed terms: attribution required, no implied endorsement, no MTA marks. Confirm commercial redistribution is permitted before shipping to paying customers (needs-decision). Mileposts/interlockings are not published.

Effort

Acceptance criteria

Lines and stations render with MTA attribution.
A GTFS-rt alert appears on the affected line within one poll.
Terms check recorded in this issue before the layer is enabled for customers.
