Lubricating tram

Watch the live broadcast of the legendary Prague tram

In order to fully appreciate the importance of the Prague lubrication tram, it is necessary to recall its history. The original virgin tram T3CS arrived in DPP in 1965 directly from the ČKD Tatra manufacturing plant. This started its new working phase which, despite various degrees of maintenance, technical modifications or complete reconstructions, continues in the articles of our corporate magazine DP kontakt (February 2015 and December 2016).

Lubricating tram

Having reached the mileage of 120 thousand kilometres in January 2016, the lubricating tram was suspended in the Hostivař tram repair shop for regular maintenance. However, the scope of the maintenance gradually changed into reconstruction and the lubricating tram thus experienced both the fixing of the old features and adding the new ones. At random we can mention new doors, cabling for cameras and the fixed seat or driver’s panel in the cabin. However, the most important changes are visible to the naked eye: new paint and water tank. Why does the lubricating tram need a water tank? Škoda 15T trams are being additionally equipped with the lubricating device, which “threatens the lubricating tram’s life”, and that is why the project of a sprinkler vehicle originated – during summer months the vehicle will water tram objects planted with grass.

The reconstructed lubricating tram was ceremonially introduced in the Těšnov turning loop on Monday, 19 December 2016. However, to everyone's surprise it was decorated in Christmas theme, carrying the traditional symbol of Christmas on its “body” – an illuminated angel. Christmas has always ended on 6 January, i.e. on Epiphany. We also symbolically ended Christmas on this day, by taking the decoration down.

Extension of functions

Already last year, the lubricating tram got, during the fixing, wide range of new functions, among other things also the tank for watering of grassed lines between the tracks. Now another function was added – real-time monitoring of air quality and temperature. The new function was installed in cooperation with the project Kaná





Dust sensor is located on the side of the tram and resembles the parking light. However, inside there is a laser dust sensor instead of a source of light. Thanks to this, you can watch online data on smog situation in the parts of Prague, where the tram is passing. The sensors measure the concentration of the airborne dust (PM2.5), i.e. particles with perimeter lower than 2.5 micrometres (um). These small dust particles very easily penetrate the lungs and pose serious health risks associated with respiratory diseases as well as cardiovascular diseases. The largest source of airborne dust in Prague is car traffic.
