This interactive map, created by Sean Marshall, compares the extent of Canada’s passenger rail network in 1955 with what was left of it in 1980 after decades of service cancellations and line abandonments. By 1980 the various railways’ services had been taken over by VIA Rail; VIA’s network would face the first of a series of cutbacks the following year (there’s a lot less of it extant today), so this map represents the public rail network at its maximum.
