If by train scene you mean the climax, yes, I absolutely agree that it looked stunning. The level of detail when Gordon blew the supports off the rails, and the rails fell was fantastic. I found no flaw in the encoding. I saw about two specks of dirt on the actual print, and that was it.
And the sound, wow, what sound. I seem to remember Cj saying he encoded this. We should all give him a big thanks and congrats on a job well done!
