The loss ledger, line by line: the interurban lost 1 June 1934 (dated); the steam road's stop gone by 12 July 1959 (bracketed) — the exact last year stands as the named gap

Passenger service left this ground on two lines, and the ledger can be printed for one of them to the day: Line 1 — the electric line (South Bend–Goshen interurban): service ended 1 June 1934, the date CERA Bulletin 132 gives the South Bend end of interurban service; Osceola's regular station at mile 10.1 closed with the line, and the power house's work ended with it. That line of the ledger is closed. Line 2 — the steam road (by then the New York Central): trains stopped at Osceola through the line's passenger century — the agent from 1863, the gazetteer's "on the L S & M S Ry" in 1884–85 — but the last year of the stop is not in any record reached, and this section brackets it instead of guessing it: the New York Central's system timetable effective 12 July 1959, read for this section, indexes Mishawaka, Goshen, La Porte, Ligonier, Waterloo and South Bend to its Chicago–Toledo tables (Tables 7–8) and does not index Osceola — with the timetable's own caveat printed beside the finding, that its index "do[es] not include all stations served by the New York Central System." The honest ledger line therefore reads: passenger stops at Osceola ended on an unrecovered date, no later than the 1959 timetable's evidence and after the depot's documented life; the exact year is the gap. What was never lost, because it never existed: no branch, belt or second interurban passenger service (item 8 above). What remains: freight only — Norfolk Southern's Chicago Line, from the 1998 Conrail division — with Amtrak passing without stopping (item 9). The ledger closes the leg at bracket strength, and its one undated line carries its settler on its face.
