PseudoProgrammer and I have started a project to build railroads with gobbed modules segments. So far, we've modelled:

>> Tilt lead-in track
>> Straight tilt track
>> Support arch
Check out the first good application of them (we discarded a previous attempt with misaligned curves) here, called the iRailRoad or IRR, so named because the colors remind me of the Ikea color scheme:
