I'm not entirely sure the most remote areas of the E&N need to become a trail. It's not like many are gonna hike from Victoria to Courtenay.
The Duncan - Lake Cowichan trail on the former railway bed has local users, and currently no good connection exists to the Galloping Goose further south. Victoria is not needed for a multi-user corridor to work, but of course it would generate sa few more users on the corridor further north. What works for the Cowichan Valley would work for Nanaimo to Courtenay.
All that would be needed is fine crush, not asphalt, similar to the western portion of the Galloping Goose. The key to building the bike path cheaply is to use the rail bed and existing structures. Safety barricades on trestles would be needed, similar to those on trestles north of Sooke in Sooke Potholes Provincial Park, on the Galloping Goose.
The E & N trail in the Capital Regional District is about as costly a trail as one can get, as a completely new parallel path and bridges were built. A Courtenay to Duncan trail would just need fine crush and safety barricades for trestles. Rail removal could provide salvage funds to pay for both rail and old tie removal and disposal.
