Caption: On a gorgeous April morning, (at the time) recently re-activated RS23 503 is back doing her thing, as they drill cars in Tillsonburg after making the trip down from Salford earlier. The hogger gives a nice touch of the throttle as they shove a cut, releasing the notorious MLW/ALCO smoke that we all love. Great crew and a great chase, although it wasn't long before the clouds rolled in. Glad I got the best of the morning light at least. Recently, this unit has been sidelined once again after a few weeks/months back on the road last year. Currently the only MLW in active service on the OSR is RS18, 182. Better than nothing, but never take advantage of these old girls. Never know when you'll have your last shot.
