>> FACTORIES - MANUFACTURING PROCESS

Austrak's system is a long-line method of making concrete sleepers.

In the system, a mould makes four sleepers side by side and a number of these moulds (typically 40 to 80) are assembled end to end to form a bed. The number of beds in a factory determines the production rate and is designed according to the market's needs.

The process used to make the sleepers with the long-line system is summarised briefly here:

1. Bed preparation
2. Prestressing
3. Pour concrete
4. Curing
5. Destressing
6. Cut sleepers
7. Inspect, test and install
8. Stockpile/loadout
