I recently purchased the July 20, 1907 Intercolonial Railway Timetable on eBay for a price I'd rather not mention (*cough* $24.88 US *cough*, actually quite a bargain). I have scanned all 24 pages and put them online for your viewing pleasure.
There are lots of interesting details in this timetable. I was amused to note that the Indiantown Branch was still in existence at this time, served by a single mixed train. That branch went southwest from Newcastle and basically paralleled the Northern & Western line that became CN's Miramichi subdivision.
Go view and enjoy!
