Prague was the first city in Czechoslovakia to introduce modern trolleybuses. Only a few other trolleybus systems existed previously in the Czech lands – in České Velenice (Gmünd) and České Budějovice[2] – using the same overhead system as the Electromote, the predecessor of all trolleybuses.
Trolleybuses operated in Prague during two separate periods. The first trolleybus system was opened in 1936 and it lasted until 1972, when it was closed.[1] After precisely 45 years, a new trolleybus system was opened in Prague in 2017.
