Even having to look for a split second means its great modeling, esp. in Z.
It helps that the couplers aren't visible at this angle. I clicked on the link, and there are other locos where the pilots are filled in and that would have been an even better illusion.
Probably a separate thread, or maybe this one could morph to other realistic photos we have seen. But it reminds me of a long ago MR or RMC cover with a BW shot of a cab forward sitting at a roundhouse. Modeler was Paul? I think. It was the first photo I ever saw (circa pre 1970) that made me look twice.
