On 27 September, from the afternoon until late at night, a special tram, the ScienceExpress, will run on tram line No. 47. Thanks to the cooperation between BKV and the Bay Zoltán Research Centre, passengers can travel by the "knowledgeable" vehicle for free. ScienceExpress welcomes young and old from 3 p.m. until 11 p.m. with three research stations.
