"The project contains 6 Work Packages (WP) and the total duration has been 36 months.
WP 1 Analysis of the current situation in the selected section of the railway lines where the DiNTRA sleepers must significantly increase the lateral resistance of the track
COMPLETED 100%
RESULTS
Characterize the problem. Compare current situation with the installed DiNTRA sleepers, recording and analyzing the data by modeling the transverse dynamics of the track
WP 2 Full-scale demonstration item in the DiNTRA sleeper operating environment for metric gauge tracks
COMPLETED 100%
RESULTS
- Complete sleeper renovation project for the metric gauge demonstration section
- Homologation and validation of the design of the DiNTRA sleeper for metric gauge track
- Manufacture of DiNTRA sleepers for track assembly
- Installation in a full-scale section that has made it possible to demonstrate the effectiveness of DiNTRA sleepers in the metric gauge operating environment
- Validation tests: Carried out by structural monitoring of the section, through the implementation of a high precision sensor system that has allowed the behavior of the sleepers to be studied in real conditions
TECHNICAL CONCLUSIONS:
The benefits of the DiNTRA sleeper on the railway infrastructure reach their maximum in curved sections with reduced radius of metric gauge, as they are the most sensitive to suffering misalignment.
The DiNTRA sleeper provides an increase in transversal stability to the infrastructure compared to the conventional sleeper.
A hitherto unknown phenomenon has been detected. We have called it ""REVERSE CENTRIFUGAL THRUST"" and It manifests itself when the train crosses the project section at certain hours of the day, due to the variation of the thermal gradient to which it is subjected.
With the results obtained, DiNTRA solution can be considered as a good alternative to minimize lateral instability.
The delay of this work package was one of the reasons that forced us to request two amendments to extend the total duration of the project by 12 months.
WP 3 Optimization of manufacturing, transportation and installation process of DiNTRA sleepers. Homologation for international and Iberian gauge tracks
COMPLETED 100%
RESULTS
Optimization, design validation and HOMOLOGATION according to international standards.
Document with all the homologation requirements demanded by ADIF in accordance with the strictest European standards for all gauges of interest (metric, international and Iberian)
Set of guidelines and technical specifications with the optimization and quality assurance of each process involved in the manufacture, transport and installation of DiNTRA adapted to potential international clients. Therefore, the processes are easily replicable in all markets.
WP 4 Full-scale demonstration element in the operating environment of DiNTRA sleepers for Iberian and international gauge tracks through an optimized process
COMPLETED 100%
RESULTS
- Complete sleeper renovation project for the demonstration sections
- Manufacture of DiNTRA sleepers for track assembly
- Installation in a full-scale section that has made it possible to demonstrate the effectiveness of DiNTRA sleepers in the Iberian and international gauge operating environment
2 phases:
1_ Iberian gauge developed in the Port of Santander
2_ International gauge developed at the Adif Maintenance Base in Olmedo
- Validation tests: Carried out by structural monitoring of the section, through the implementation of a high precision sensor system that has allowed the behavior of the sleepers to be studied in real conditions.
Both test campaigns were successfully completed.
With the results obtained, DiNTRA solution can be considered as a good alternative to minimize lateral instability.
The delay due to obtaining the permits was the other reason that forced us to request two amendments to extend the total duration of the project by 12 months.
WP 5 Exploitation and dissemination
COMPLETED 80%
RESULTS
Market analysis and identification of current and future competitors
Business model: exploitation strategies and marketing plan
Dissemination plan: it has been developed in line with market trends, ensuring transversal coherence between all communication channels and actions in collaboration with potential partners, end users and interested parties (manufacturers precasts and railway infrastructure managers)
Through homologation, DiNTRA has been included in technical specifications of Adif. This is a key action that gives a lot of visibility and brings a high technical relevance to the project.
National and International visits to potential clients, congresses and technical events have been attended.
""REVERSE CENTRIFUGAL THRUST"". Object of independent detailed study to prepare a scientific article that is intended to be managed through the service offered by the European Commission to disseminate the successful results of its projects and which will in turn serve to complete the doctoral thesis of the person who has served as technical director in the DiNTRA project.
WP 6 Project Management
COMPLETED 100%
RESULTS
Technical coordination
Monitoring and controlling the use of resources and administrative supervision of the cost incurred.
Quality monitoring and risk assessment"
