37518 leads 45407 not long after crossing the Fillan Viaduct just north of Crianlarich and turns into the curve to the west. A different line up to the usual on the West Highland - normally when the Jacobite stock heads north the two Black 5s are at the front, 37 in the rear. On this occasion 45212 was on the rear. (I asked - does anyone know why - thank you to the several replies to this. This formation was due to fire risk, ironically enough as I stood there in the bucketing rain.)
