Innovate models have been developed for railway transition zones (RTZs) providing new insights regarding degradation mechanisms. The models also enable relating existing observations to the mechanisms.

The project also delivered a design criterion for RTZs stating that, to prevent differential settlements, the flow of energy through RTZs should not be obstructed to ensure that its magnitude is as uniform as possible; there should be no energy concentrations in case of non-uniformity. The criterion clarifies why existing transition structures are often not effective. A new transition structure SHIELD (Safe Hull-Inspired Energy Limiting Design) has been devised based on it.
