Overlapping Gauges
Bangladesh is tackling its break of gauge problem by adding a third rail to its broad and narrow gauge lines, so that it becomes a mainly dual-gauge system. The new Jamuna Bridge that links the east and west rail systems is four rail dual gauge. At some stage the government of Bangladesh may choose one gauge over the other and convert to a single gauge, but there are no immediate plans for this.
Bangladesh's neighbour to the east is also 1000 mm gauge, should the missing link ever be built.
A variation of overlapping gauge is to extend a railway of one gauge into territory that is mainly of another gauge so as to avoid transhipment of specific traffic. For example a 1524 mm gauge line from an iron ore mine in Ukraine to a steelworks in Slovakia, which now may be extended into Austria.

Famous quotes containing the word overlapping:
“The absolute things, the last things, the overlapping things, are the truly philosophic concerns; all superior minds feel seriously about them, and the mind with the shortest views is simply the mind of the more shallow man.”
—William James (1842–1910)
