During the operation of stations railway infrastructure is depreciated, the

size of train flows constantly changеs, which s periodic reconstructions and

renovations. The station throat is the place that should provide an opportunity for parallel

performance of a larger number of operations to ensure traffic and shunting work as well as

traffic safety. Therefore, it is proposed to use its relative occupancy to assess the throats for

an estimated period with a maximum number of movements. In order to illustrate the

suggested methods, the paper examines both the historical development of the passenger

station of Sofia and its rehabilitation in recent years. The paper analyses the western throat

built in 1974 and its possibilities in terms of train and shunting operations. The design mouth

scheme during rehabilitation and the proposed scheme with the same number and type of

switches are examined. Their relative employment for an estimated interval of 180 minutes

with 48 implemented movements are determined for each of the three schemes. The obtained

results have confirmed that one of this indicator can be used to assess different designs of

throat schemes and the optimal one is that with minimal values of the examined indicator.
