I doubt any rail project anywhere in the World was free of Politics at any time from inception to completion.
Although the US was mostly built by Private enterprise, licenses, permits and permissions needed had a Political finger in 'The Pie' in some way.
This 'We like Trains but 'Not in MY backyard' syndrome is one reason why a proposal to open the Mudgee Branch between Gulgong and Kandos was howled down by the residents of Mudgee so the proposal withered on the vine as the 'NAY's' far outnumbered the 'YAYS'.
It was around this same time, May of 1869 the Main Western line was 'opened' to Rydal (NSW) to allow regular Passenger and Goods services to operate between there and Sydney.
No official opening was carried out at the time as the line was still being constructed towards Bathurst and Rydal was only a temporary Terminus for next 2 or 3 years with Cobb and Co coaches filling in the gap.
