The timetable

Live delays Train positions Timetables Unofficial source

Live delays, train positions and timetables of ŽSR / ZSSK in Slovakia, recorded since 28 Sep 2026 from GTFS-RT and GTFS feeds, and from data published on data.slovensko.sk, which the archive converts to GTFS-RT.

Pick a day on the calendar. Each day is one file with everything recorded that day, in Slovakia local time. You choose the format on the next page: a spreadsheet (CSV, opens in Excel, LibreOffice or Google Sheets) or Parquet (a compact table format for code).

37 days ready to download. The archive has data for this source since 28 Sep 2026.

Choose the first and last day: you get one zip with a file per day.

The planned timetable: stations, routes, trips and times. It comes as GTFS, the standard timetable format, one Parquet table per GTFS file. 3 versions stored, a new one when ŽSR / ZSSK changes the coming week’s trains.

All versions as Parquet tables

Tools that need a GTFS zip: pip install gtfs-parquet, then gtfs_parquet.write_gtfs(gtfs_parquet.read_parquet(folder), "gtfs.zip") on a folder of the tables. This version was stored on 28 Oct 2026, 13:54 and is the current one.

Accounts are free: you sign in with a code sent to your email, no password.

Every day is a Parquet file at a fixed address. Read it straight from DuckDB, Polars or anything that reads Parquet over HTTP: only the columns and rows your query needs are downloaded. You need a free API token from an account.

Live delays on 15 Oct 2026, with DuckDB

INSTALL httpfs; LOAD httpfs;

-- The final delay of each train at each stop, in minutes: the 20 largest
SELECT route, stop_name, scheduled_arrival, arrival_delay_min, delay_source
FROM read_parquet('https://data.train-archive.eu/daily/provider=sk-zsr/service=TripUpdate/date=2026-10-15.parquet?token=YOUR_TOKEN')
WHERE trip_status = 'scheduled'
ORDER BY arrival_delay_min DESC NULLS LAST
LIMIT 20;

The same, in Python with Polars

import polars as pl

token = "YOUR_TOKEN"
day = pl.read_parquet(f"https://data.train-archive.eu/daily/provider=sk-zsr/service=TripUpdate/date=2026-10-15.parquet?token={token}")

# The final delay of each train at each stop, in minutes: the 20 largest
print(
    day.filter(pl.col("trip_status") == "scheduled")
    .select("route", "stop_name", "scheduled_arrival", "arrival_delay_min", "delay_source")
    .sort("arrival_delay_min", descending=True, nulls_last=True)
    .head(20)
)

Or save the file, with curl

curl -L -o sk-zsr-TripUpdate-2026-10-15.parquet \
  'https://data.train-archive.eu/daily/provider=sk-zsr/service=TripUpdate/date=2026-10-15.parquet?token=YOUR_TOKEN'

Replace YOUR_TOKEN with one of your API tokens. Delays are in seconds in the Parquet files; the examples turn them into minutes.

Stations of the current timetable

import json, urllib.request
import polars as pl

base, token = "https://data.train-archive.eu", "YOUR_TOKEN"
latest = json.load(urllib.request.urlopen(f"{base}/sk-zsr/static/latest.json?token={token}"))
stops = pl.read_parquet(f"{base}/{latest['tables']['stops']}?token={token}")
print(stops.select("stop_id", "stop_name"))

Unofficial source: the operator does not publish all of this data as GTFS, and volunteers convert or relay part of it. It can stop at any time.

From 10 to 19 October 2026 about a quarter of the updates matched no train of the timetable the archive had (30 September; ŽSR's uploads of those days are no longer published), so those days lack the planned stops of many trains: treat them as doubtful. 20 and 21 October were rebuilt against the timetable of 22 October (every update matched).

875 stops in the latest timetable (every stop: the timetable does not mark stations).
