Hello all common

 

I am now starting to lay track on my flat layout which will be conventional tubular lionel o gauge track. I will be running conventional postwar trains and Lionel legacy trains. Most of my layout will be 72 and 54 I'n radius. Please advise the rise per foot in a 3% grade and a two and a half percent grade. I hope a 3% grade will not be pushing it.

 

Please give me your suggestions on track elevation in general and what type of material to use for the elevation. At this point I have a lot of foam and I plan to use it for the elevation base. I also have lionel postwar trestle set but I feel the phone would be a better base. Please advise,

Jerry,

   There was a post in the last few months where one creative guy combined 2 Lionel trestles with extra cross bracing and painted it all a dark color like black or brown. It gave the Lionel trestle a nice realistic look.

   In general, you can try by trial and error to see what looks acceptable. I had a layout a few years ago that I tried to calculate the grade using a scale ruler...using your own judgment comes out just as well in most cases.

This will vary a lot depending on the loco (Magne-traction or not, in particular) and the weight and rolling characteristics of the cars. Postwar Lionel wheels sets are not particularly free-rolling and some of the old cars are quite heavy.

 

You best bet is to do tests with your own equipment to see what works, before committing to a standard for a permanent layout. With smaller up-and-over layouts it can be tedious to control the speed for upgrade and downgrade.

 

I've tested my Postwar Lionel #2343  F3 set (dual motor Magnetraction in one unit) with about 10 cars on an 8% grade. It can haul it, but probably not what you want for regular operation. However I did build 30+ feet of 8% grade to connect my floor layout with a table layout. Magne-Traction locos can handle shorter trains on this. Locos with traction tires can potentially burn up motors as mentioned in the recent Christmas tree layout topic. Some Postwar locos with typical spur-gears will run away on an 8% downgrade.

For most layouts, grades in the range of 2% to 4% should be manageable with good motive power. I have grades up to 5% on an HO layout operated successfully for 30+ years.
