PD CEN/TR 17373 is the European standard on railway vehicles that investigates railway position and calculate buffer overlap.
The purpose of PD CEN/TR 17373 is to analyse the conducted investigation and evaluation of lateral displacement and buffer overlap between each two specified vehicles of different train sets for defined running cases in curves.
For this purpose, the types of vehicles defining the train sets and different operating conditions are specified. The position of the vehicles on the track at the moment of maximum lateral displacement (minimum buffer overlap) is recorded during the calculation.
The worst cases of lateral displacement and buffer overlap between two coupled vehicles as well as relation to formulae in EN 15551:2009 are analysed.
PD CEN/TR 17373 on railway rolling stock is useful for:
Rolling stock referred to vehicles that move on a railway that usually includes both powered and unpowered vehicles, for example, locomotives, railroad cars, coaches, and wagons.
PD CEN/TR 17373 provides the calculation of the coefficient for the position of the wheelsets of the bogies in the curve.
PD CEN/TR 17373 specifies the location of the vehicle in the track as well as the displacement and position of the vehicles in the S-curve.
PD CEN/TR 17373 provides the formulae for calculating the minimum half-width of buffer heads to avoid the overlap of the buffers of any two vehicles running on a given S-curved track.
Comparison of the results of investigations and buffer overlap of investigated vehicles is mentioned in PD CEN/TR 17373.
Moreover, PD CEN/TR 17373 could assist you in determining railway position while moving along a straight track providing signal protection to comfortably stop at the stop signal. In this manner, the rolling stock industry is making an effort to reduce its environmental impact and increase performance while remaining attentive to economic constraints.
