Official abstract: This document provides the public with notice that, on November 1, 2026, the Northern Indiana Commuter Transportation District (NICD) submitted a request for amendment (RFA) to its FRA-certified positive train control (PTC) system. NICD intends to replace several Cisco Networking devices as part of a PTC hardware replacement project. This will involve three of NICD's trains, Trains 35, 432, and 601, operating without PTC technology for approximately three hours from 11:00 p.m. to 2:20 a.m. on one date that is to be determined following FRA's review and approval. FRA is publishing this notice and inviting public comment on NICD's RFA to its PTC system.
