Construction of the Seymour railway line was approved on June 3, 1870, and completed March 31, 1872.
The first train crossed the Goulbourn River on August 26, 1872, and the official opening of the line was held on September 2, 1872.
Crossing the Goulburn River before the official opening date ensured the safety of the newly-constructed bridge.
The railway created business opportunities and quicker and safer travel between Melbourne and Sydney.
Farmers could send products like grain and stock quickly and safely over longer distances and the need for timber in the growing cities could now be met.
The railway workforce grew enormously. Maintenance crews, engine drivers and watering and refuelling crews meant the population of towns like Seymour along the railway line grew.
Some towns, like Avenel and Longwood, were relocated to capitalise on the benefits the railway brought.
Ten years after its opening, up to 70 trains were passing through Seymour each day.
