Bear with me, I've not gone mad but here's a very technical question...
Do class 90s make a lot of particulates? Either from brakes or traction motor brush wear or something else?
Reason is ask is twofold. One, whenever I see one pass, it's not uncommon to see it enveloped in a sort of greyish cloud, even at low speed so I don't think it's dust off the track.
Secondly, I'm currently sat in the first row of coach K on the GEML heading into London, right behind the loco. Something is making my nose run and chest tighten, and the curious Mk3 smell (a mix of mustiness, grease and the je ne sais quoit we all know) seems somewhat amplified and I overlaid with a smell that is redolent of the smell you get on the tube.
Makes me wonder if this isn't the best place to sit!
