The assessment of the dynamic behaviour of [https://www.designingbuildings.co.uk/wiki/Railway railway] [https://www.designingbuildings.co.uk/wiki/Bridge bridges] often shows a marked difference between theoretical calculated behaviour and that measured by [https://www.designingbuildings.co.uk/wiki/Inspection inspection]. Typically, this would be in the form of lower measured natural frequencies than calculated by the structural analysis. This is often attributed to additional [https://www.designingbuildings.co.uk/wiki/Stiffness stiffness] provided by the ballast and the track that are usually not included in the strength [https://www.designingbuildings.co.uk/wiki/Model model].<br />

Increased stiffness would generally lead to higher natural frequencies, and high mass to lower natural frequencies. Perhaps there is a typo in the above paragraph?
