Data Loggers for Queensland Rail’s Tilt Train

Plug and Play Replacement of pre- existing Data Loggers for Queensland Rail’s Tilt Train


Queensland Rail‘s pre-existing data recorders were a part of an older generation, supplied through the train manufacturing process. With these recorders, data retrieval was a strenuous, lengthy and not always successful process. This pushed Queensland Rail to seek a cost effective means to replace the existing event recorders with a reliable and proven alternative – the Hasler TELOC® 1500.

The Challenge

The following factors had to be considered:
– Minimal or no disruption to scheduled services: All work on the trains was to be carried out overnight and only one train was available per night
– No rewiring or reworking was permitted
– Recorder dimensions must be identical to the previous solution
– All existing event recorder functionality must be kept
– Future proofing


Due to the short timeframe to commission the units – as access was only available during the evenings, it was critical to get the replacements right, as QR could not operate the trains without an event recorder.
Every challenge was overcome with in-house state of the art bench testing in Hasler Rail’s laboratories in Berne, Switzerland and over two nights, the Hasler TELOC® 1500s were success- fully commissioned onsite.
