For the Delft Cluster project “Railway Transition zones” extensive field-testing has been performed. Testing took place on the railway track Gouda-Goverwelle (GoGo) on a culvert and on a Switch. Many different parties were involved in the testing and numerous different types of tests were performed. Al the different tests ad up to a large amount of data supplied by different parties and thus supplied in different formats. This report is a part of a series of factual reports, which give a complete overview of al test performed and their results. All reports are written in the same format and tests are named in similar fashion. The reports also describe the structure of a database that contains all data. This database is supplied digitally along with the reports. The complete series of reports consists of: A. Field survey. 1001069-000-GEO-0004 Factual report soil investigation B. Short-term measurements May 2008. 1001069-000-GEO-0003 Factual report short term measurements 2008 C. Short-term measurements April/May 2009. 1001069-010-GEO-0004 Factual report short term measurements 2009 D. Long-term measurements. 1001069-000-GEO-0005 Factual report long-term measurements. This report (A) gives a complete overview of all the long-term measurements and the results. The long-term measurements focus on levelling. In Chapter 2 and 3 all measurements are presented and discussed. To enable further studying of the data, the original data is available. Chapter 4 shows where the data can be found.
