The first four photo's were taken at the Grand Canyon and the rest on the road out of Tucson. The trains are immense - some I passed were quintuple headed. Others were top and tailed and some with a loco halfway along the train length. I clocked a stationary train at more than one mile long!
Tucson has a compact little model railway shop lodged in the Ace Hardware store on East 22nd Street. I bought an AC 4400 from there and a DCC chip. The shop staff couldn't fit the chip for me but suggested I visit the local Model Railway Club as one of their friends was quite well informed on the subject. Not only did I get a warm welcome but they fitted and programmed the chip for me on their club layout.
So I just got back from a two and a half week trip to the USA taking in Kentucky, North Carolina and Tucson Arizona. I had a great view of Tucson on the approach from my window seat on the plane. Tucson is a vast city with Davis-Monthan AFB right in the centre of town with its massive aircraft storage facility featuring hundreds if not thousands of stored aircraft from F-4 Phantoms, F-16's, B707's to dozens of C-130 Hercules and Starlifters.
I digress; also visible from the air was the massive Union Pacific freight yard also in the centre of town. This place has to be seen to be believed with trains being marshalled into mile long consists. Further north along the I-10 Interstate highway the line runs alongside the road with plenty of crossings and roadside access from the service road which is where the latest photo's were taken from.
