I don't want to open the Sight just yet, because so far the situation's not quite dire enough to require it. Simply having The Sight means I do get to use my Lore as an arcane Investigation and/or Alertness skill, and furthermore, I get a +1 when doing so.
So, I assume that unless something is sneaking up on us, I won't have to use the latter version, only the former. In that case, I'll roll it to assess/examine the general subway area. This should give me an idea of whether there's anything supernatural at play here rather than just being a subway blocked off for mundane reasons.
