In late December 2020, TVZ has sent to Tulpar works in Nur-Sultan the final batch of subassemblies for the new passenger cars ordered by KTZ, bringing the 2020 deliveries to 100 cars in total.
A 1,520 mm gauge Evolution, the GE-built demonstrator, also visited Poland. This diesel locomotive paid a visit from Kazakhstan to Poland in 2015, for evaluation by PKP LHS, the subsidiary responsible for operation of the freight-only, non-electrified 1,520 mm gauge 394 km Line 65. The visit took place in May and June 2015, following almost a 5,500 km long journey.
In our article about Prima locomotives we described problems at orders of electric locomotives from EKZ. But similar problems concern also KTZ orders of Tulpar Talgo and LKZ, both factories based in Nur-Sultan. Of the Evolution diesel locomotives, which are manufactured at the latter site, only part of the initially planned numbers were built so far.
