Not as young and flexible as you used to be? Got wiring that needs attended to under the layout, but cannot contort yourself in a pretzel to do it? Here's a great do-it-yourself layout creeper idea that will nicely fit the bill. https://www.trainboard.com/highball/index.php?threads/layout-creeper.143138/
I have an automotive creeper I used for doing my oil changes on the car - before I went out and bought a new one last year with an extended maintenance plan. I've found many uses for that useful doodad, like rolling layout halves (it comes apart in the middle into two 4x6 foot sections) in and out of the spare room, moving heavy stuff from the car to the front door, and sliding under the layout to do any maintenance and inspection work. I add a pillow for my head for comfort and Bob's your uncle and Fanny's your aunt.
Does it have an adjustable height for the body part or just the headrest? I did this to get me at a comfortable height under the layout. Not too far down or to high up with some angle to my body. One can make it to any height they need to fit their layout height. Sumner
I bought this last year. For working on the airplane but secretly knowing it'll spend more time in the train room. It has 10 height levels. I use a pillow with it.
So do the trains orbit clockwise on the North America side, and anti-clockwise on the Australian side? Or is that counter-clockwise on the North American side, and clockwise on the Australian side?
