See Spadina Subway, 1978, for a live example, with some imaginative uses of concrete. Unfortunately concrete traps the brake dust from the subway trains and you end up with grimy dirty walls and floors which require frequent cleaning (and we know how infrequent the cleaning is now). Brake dust tends to clean off tiles or glass much more easily, which is why the glass tiles were chosen for the walls on the original Yonge line. What we want is the durability and ease of cleaning of tile without the old-time tile look.
In terms of floors, the concrete floor at the Walmer Rd. exit at Spadina Stn is already deteriorating in some spots whereas terrazzo probably would hold up better to the salt that gets tracked in.
There are definitely some lessons there in those cases like not having concrete walls along the tracks and not using concrete for flooring. But I love Montreal's stations with massive concrete arches, coffered concrete ceilings, concrete columns in interesting shapes and the concrete 'light tree', for instance. Those seem like creative flourishes by planners who cared about more than just "cheap and cheerful" design but who didn't intend to build expensive palatial spaces like the Moscow Metro.
