Preliminary report released on passenger train exceeding temporary speed limit

A preliminary report has been released into an ongoing transport safety investigation into the exceeding of a temporary speed restriction by an XPT passenger train in Melbourne.

On the morning of May 24, 2022, a Sydney-Melbourne XPT service crossed the Moonee Ponds Creek Bridge in north-central Melbourne at around 100km/h.

This was above a temporary speed limit of 40km/h, placed on the 400m section, after the rough track had been flagged there the previous night.

An investigation is being carried out by the Office of the Chief Investigator, Transport Safety, which investigates rail occurrences in Victoria on behalf of the Australian Transport Safety Board.

The preliminary report details the factual information from the first evidence-gathering phase of the investigation.

“Traveling south towards Southern Cross Station, the standard gauge and broad gauge tracks run parallel to Jacana,” explained lead investigator, Transport Safety Mark Smallwood.

“However, at Jacana, the standard gauge track, used by interstate trains, deviates from the more direct (16km) broad gauge route and takes a longer 27km route to Southern Cross To accommodate this longer route, the standard gauge track included a gradual change in its mileage at this point, from 16 km to 27 km.

This effectively meant that trains on the standard gauge line passed through two sets of mileage markers from 27km to 16km, en route to Melbourne.

“The driver involved in this incident has been advised of a speed limit between 15 miles and 15 miles,” Mr Smallwood said.

The driver slowed below 40 km/h on the first 24.4 km to 24.0 km section encountered, but not on the second, where the restriction was effectively in place.

The investigation will include a closer look at the condition of the track that led to the temporary speed restriction, the operation of the train, and the processes and risk controls associated with setting a restriction. temporary speed limit and its communication to drivers.

A final report will be published at the end of the investigation.

“However, if a critical safety issue is identified during the investigation, the ATSB will immediately notify affected parties so that appropriate and timely safety action can be taken,” Mr. Smallwood said.
