Really superb app. Tried it out during recent up and down from MS-SRGM Rockfort Exp; superb timing, speed matching up and down braking, and annoucements of stations in REAL TIME. IRI HAS GONE BEYOND WHAT WAS EXPECTED. GREAT GUYS. TRAVELLING AGAIN ON SAT 21 BY ROCKFORT FROM MS-SRGM, AND RETURN SUNDAY 22ND BY TEJAS FROM TPJ TO MS HOPEFULLY.
