Nick… I'm not sure what you're doing, it sounds fascinating, mysterious and dangerous. I like it. Please let me know what path you're taking through Sydney so I can avoid the area completely... I don't want to crash a brand new $30m Waratah into your ladder!
This info from ARTC will be handy … http://www.artc.com.au/library/GI_05_loading_restrictions.pdf Also, thank you for fixing those track sections at St Marys. Do you know what happened there? Given there was a derailment there 2 months ago, I find this a spooky co-incidence... http://hornsby-advocate.whereilive.com.au/news/story/train-delays-after-derailment-at-st-marys/ "Mr Eid said the derailment was under investigation and that he believed a component from a freight train fell onto the track." …. a very large ladder, perhaps? :-) You might find this site an interesting source of tunnel information… but sadly no widths or loading gauges . http://www.nswrail.net/infrastructure/tunnel.php If you're interested in the evolution of loading gauges in NSW, I recommend a book published by the Australian Railway Historical Society called "The Electrification of Sydney and Suburban Railways" which explains the decision that lead to a new wide-bodied loading gauge adopted for construction of the Harbour Bridge and City Underground Railway… a bold move with ongoing repercussions today (e.g. you can't send a wide-bodied train such as an OSCAR any further west than Springwood without major and expensive modifications to the infrastructure -- so…. what happens to outer Blue Mountains train services once our narrow-bodied V-sets are eventually retired and replaced with OSCARs hmmm??). Finally… if you're confused by all these sizes, just remember it all gets back to the width of 2 horses asses. http://infobluemountains.net.au/rail/horse-ass.htm BJ On 16/10/2012, at 6:30 PM, Nick Hocking <nick.hock...@gmail.com> wrote: > Alex wrote > > "or a question about loading gauges that the ARTC might better answer?" > > Yes it would be better for ARTC to answer but before I bother them I would > like to know if it is at all feasable.
