Tyn6.3631 at Piaseczno Miesto. This system once ran right into the centre of Warsaw but was gradually reduced over the years.
Tyn6 was a 2-6-2 tank. This loco was steamed for a visit by British enthusiasts but had not reached working pressure by the tiem of their arrival and was therefore assisted by a vintage railcar. A sister loco was also present although neither were, by then, working on normal services but were 'in reserve'.
