Our Goal:

In our customer’s train loading facility, the operator was required to manually check every wagon loading profile to ensure it has met the rail specifications.

There are various checks to perform for each wagon profile and those included gross weight check, front bogie & rear bogies weight check, front & rear bogie differences check, number of overload wagons that still met the specs.

As a result, this takes up the operator’s time and concentration, hence reducing the operator’s ability to perform other tasks more effectively.

Since the checks can be easily missed while loading the train, the train manifest must be re-checked again at the end of train to ensure it has met the specs.

If there is any wagon not meeting the loading specs, the train will have to be pulled back to rectify the problem.

Our Solution:

To reduce the burden on the operator, the PLC was used to perform all calculations and carry out all the checks.

Alarms will be presented to the operator accordingly so they can take any action if needed.

Unlocked Potential:

With all the checks being carried out and performed within the PLC.

The checks are more reliable, faster and highly accurate.

The operators no longer need to compute and check each wagon load.

They will only need to focus on loading process and if any alarm on the screen is displayed rather than checking numbers
