Minor safety issue
As the re-signalling of Cootamundra neared completion it became
necessary to undertake control table and software development
concurrently to meet the targeted commissioning date. Normally
control table and software development is done sequentially to
ensure that all the control table logic is fully reflected in the
final software and associated validation/testing processes.
