First T coach started test runs

In early March 2025, the first single-deck gabarit T (T loading gauge) prototype car of Model 61-4533, built at TVZ, has begun approval testing. At the VNIIZhT test polygon in Belorechensk, specialists will check the its running characteristics, perform strength and braking tests under various loads, determine the parameters of external noise, vibration, ECM, and suchlike.

In contrast to the existing 1-VM loading gauge, the length of the gabarit T car has increased by 73 cm and the width by 28 cm. The corridor will be 9 cm wider, the sleeping compartments will be 15 cm longer and one passenger compartment has been added. This has made it possible to increase the level of comfort and capacity (by 11%).

The final assembly of the second prototype, the 61-4535 „shtabny vagon“ service car, is currently underway at TVZ.  After completing the entire cycle of tests and obtaining a certificate of compliance with the requirements of the TR TS 001/2011 technical regulations of the Customs Union, TVZ will start batch production for RZD.
