✦ Synopsis

We identify the physics behind the results of recent measurements (Nature 403 (2000) 59) of electron transfer between the edges of two two-dimensional electron systems (2DES). We ÿnd that a consistent explanation of all of the observed phenomena is possible if the barrier between the 2DES is surrounded by a strong potential well that supports quantum railroads of edge channels that, in the presence of disorder, exhibit directed localization.
