Translated Description from PIKO: New for 2023: pressure variant of the DR cement silo wagon in Ep. IV. The PIKO TT model of the cement silo wagon represents a prototypical replica of the Ucsv dust freight wagon serve. The toggle closures of the openings of the silo holders, which are necessary for safe transport, are also shown exactly. The cars can be used prototypically in block trains as well as in attractive mixed freight trains. The model has TT close couplings!
