Yes and no - I'm not convinced it's for the same system, because the "pink ones" are for traffic signals (vehicle/automotive traffic signals). There aren't any signals like that at Seagram - only the railway crossings, and there's no inductive loops on the North side of the tracks - only two on the platform. So I'm more inclined to think the ones that I spotted at Seagram are to tell a signalling system that "a train is sitting here" when it covers both of the loops fully.
