Case Study: Gary McLean achieves faster, more accurate rail design with 12d Solutions

Gary McLean - Customer Case Study

The customer, Gary McLean, faced a challenge on the Adelaide Hills Rail project involving the precise design and plotting of rail infrastructure, including ballast, sleepers, and rail profiles on correct cant. A critical requirement was to calculate the exact ballast depth under the sleepers at both high and low rail locations to ensure it met the minimum design specification, as this depth directly supports significant train axle loads.

12d Solutions implemented a solution using their 12d Model software with the 12d Track macro. This allowed for the creation of a super alignment, the application of cant design models of the track infrastructure. The process enabled precise draping of rail strings onto the formation design to validate ballast depths and generate quality assurance reports. The use of 12d Model with assisted the design process, and ensured the client that the critical design criteria were
