tapSTRAIL in Melbourne, Australia

FACTS

Location: Melbourne, Australia
Client: Metro Trains Melbourne
Products: tapSTRAIL
Length/Quantity: 4 x 24,3 m
Conditions: AS60kg rail, Low Profile Concrete Broad Gauge Sleeper (1,600 mm)
Period: November 2019

 

ADVANTAGES

• independent sleeper spacing > smoothly and fast installation
• 900 mm panels > high installation capacity
• suitable for lightly frequented level crossings
• durable & low-maintenance

 

A QUICK OVERVIEW

The Melbourne Metro was upgraded and connected to existing rail lines.

In the process of these track works an existing level crossing was renewed.
Two-way vehicles use this level crossing to access the rails.

A special feature: the platform covers four tracks with different track centres.

Both inner and outer panels of the tapSTRAIL system were used.
Due to the flexibility of the outer panels, the different heights of the individual tracks could also be compensated for without any problems.

tapSTRAIL enables the maintenance vehicles to easily cross over and track onto the rail.

  – No interference with the substructure
  – No levelling layer required
• Quick installation > short blocking periods

 

A QUICK OVERVIEW

In recent years, the available track and road blocking periods have become shorter and shorter.

This means that there is less and less time for installing level crossings. For exactly this reason, it was decided for this project to use the innoSTRAIL system, which works with any sleeper spacing, in combination with the concrete broad kerbstones that do not require a prefabricated foundation.

The installation was carried out by 4 fitters from the track construction company Meier + Jäggi AG.

Just three hours, that was all it took to install the entire 5.40 m level crossing.
During this time, all kerbstones as well as inner and outer panels were laid.

As the B-Kerbstone is laid without concrete, there is no curing time.
This means that the level crossing can be used again immediately after installation.

A quick combination, indeed!
