Description
This report comprises deliverable D 1.2 from Work Package 1, defined in the contract documentation as "a report on the age profile and condition of existing European rail-way bridges, transition zones and embankments, subdivided by construction material".
Although the contract deliverable mentions that bridge condition would be reported, it was thought that seeking such data was likely to inhibit responses from the railways approached, since they may well regard it as sensitive. To ensure the return of as many completed replies as possible this topic was not included in the questionnaire, since it is not relevant to the scientific aims of the Sustainable Bridges project. Existing bridge condition will be more important in gauging uptake of the scientific advances coming out of the project and will probably be a topic in future questionnaires. Never-theless, some indication of bridge condition across Europe is available in the “mainte-nance” survey data reported as deliverable D1.3.
The data presented within this report has been collected from the 17 European railway administrations that responded to a questionnaire initially formulated following prelimi-nary discussions within WP 1 and amended at the request of the other WP leaders.
The report discusses the methodology used in obtaining the data, the success in ob-taining data from those requested to provide information and the reliability of the data obtained. It then goes on to present the analysed data in outline.
The questionnaire used for this data gathering is reproduced as appendix A1. Detailed spreadsheets, giving the breakdown of the data by railway are given in as appendix A2.
