The major advance was made in the complete elimination of the "washboard" effect, in the Dietlikon test track design (1980-83) by stiffening the "guideway" which was a pair of naked cables in Mannheim, with an aluminum rail extrusion over the insulated pair of cables, and increasing the frequency of the running rail supports from one hanger cable support every 3.5 meters to one in every 2.5 meters.

An "equalizer" joint among all cables (as illustrated in the UMTA Assessment Report) was installed at the lowest point of the Suspension Cable (where it meets in elevation the Rail Supporting Cables). This eliminated excessive relative movement of the Suspension Cable with respect to the rails.

The Mannheim vehicle and many of its features, (which performed with remarkable system availability of 99.6% over 5 months) are being replaced with improved US designed, professional transit vehicle designs, satisfying all current transit vehicle standards including ADA, and using proven subsystems. Vehicle capacity has been increased by using longer and wider modules, with or without doors and special end modules for wheelchair access, emergency exit door and chutes.
