This Londoin trolleybus was at the 1983 Acton Works open day celebrating 50 years of London Transport.
Those trolleybuses are Škoda 9TrH (in Soviet Union 9Tr - only 2 doors, 9TrH - 3 doors) ... but Škoda 9TrH + Škoda 9TrH = Škoda 12TrH (the same with 9Tr+9Tr=12Tr) ... the had the depo number 2-800 - 2-900 (not sure with which number they started, but they ended with the 900. The first number (2) shows the depo number) ... the last such Trolley was used in 2000 ... I heard that atleast one such trolleybus from Riga is in a museum in the UKspsmiler said:Note how the front vehicle does not use its trolleypoles and is both physically and electrically connected to the rear vehicle. If I remember correctly these are trolleybuses of the type "9tr".
