L-Girder is fine for some applications, but with a solid table top all you really need is good dimensional lumber on edge (perpendicular to the plywood). Glue'd and screw'd it should last a long time and be sturdy. Basic box frame construction is often poo-poohed by the L-Girder afficianados, but really each is a fine technique for its own purpose. If you are building a solid-top layout (4x8, 4x6, etc) from a solid sheet or sheets of ply, then a basic box of 1x4's or 1x3's will suffice. However, if you are planning to go with cookie cutter roadbed and many elevation changes then L-Girder has a few more advantages.
