Wowsers! That is a great looking layout you have, Karl. The Bachmann model fits in well with the Altas S units.
My second alco arrived, a P2K S-3. I've added a pic with her next to my HH600. This is my first P2K loco I am impressed by the level of detail on the Proto shells. After seeing what the S-3 is like, I want to get an undecorated Sw1200 now. I'm not so sure about the mechanism as it has an open frame motor. I think a company called A-Line has replacement motors. Not sure if I'll go an Atlas mech, Bachmann mech or just rebuild the P2K mech.
I will have to try and finish a few loco projects before I get carried away buying more stuff. These two have to wait until the EMD switchers are done (still need to order a few detail parts). At present I have only finished one engine, the Bachmann GE 45 tonner in the second pic.
I included an extra pic or two of the GE 45tonner straight out of the box next to an Alco D531 export series in NSWGR 1960's livery. The D531 was intended as a narrow gauge loco for 3'6" and meter gauge railways, but was used on standard and broad gauge in Australia. They were also employed in South America (Peru I think), Malaysia, Thailand, and I think Pakastan might have had some.
