I am a new modeler building a layout, and I have a question about starting a grade from level track. I assume that an abrupt grade start might lift the trucks off the track or cause uncoupling. I plan to transition into the grade by building an increasing step out of two or three layers of thin plastic or cardboard and then butting the grade into this.
Is this transition necessary, and am I on the right track? Any suggestions or references to web pages, etc., would be appreciated.
You are on the right track, conceptwise, about needing the transition to avoiding operational problems such as uncoupling, jamming the uncoupling pins into the ties of the track, causing a short if the front of a metal locomotive touches the rails, etc. You might consider elevating the the supporting subroadbed at progressively higher lengths to get the same effect. Just try to avoid joints in this transition point, in either the subroadbed, roadbed, or the track itself.
Yes you’re right about needing a transition, and Leon was right on with his suggestion.
What are you using for benchwork, flat plywood, open grid, l-girders, other? Depending on how you are doing your benchwork there might be a suggestion or two for starting the grades.
Remember if you use the Woodland Scenics risers that you have to transition back to flat at the end of the “rise”. Otherwise you will be creating a “launching ramp”, which can cause some operational difficulties…
