Zusammenfassung:	A convertible trailer for road and rail operation has four rail wheels and two road wheels. Each road wheel is within a road wheel assembly which connects to a main pivot or axle on the trailer, around which the entire assembly can rotate and thereby separating the road wheels from direct connection to the trailer. A lift, which may be motorized or hand controlled, raises and lowers the entire trailer by raising or lowering a foot which engages with the ground. When raised sufficiently and a locking mechanism disengaged, the road wheel assemblies may pivot on the pivot or axle. This pivoting allows the wheels to be locked in high position out of the way for rail operation. With the road wheels disengaged, the trailer may be lowered allowing the rail wheels to contact rails for railway operation.
