273 series

The 273 series is a Japanese tilting limited express electric multiple unit operated by the West Japan Railway Company since April 2024.
==History==
Information for the 273 series sets was revealed in February 2022, stating that this train would be introduced in fiscal Spring 2024 to replace the 381 series sets used on the Yakumo service. A total of 11 4-car sets are slated to be produced and introduced onto the Yakumo service.
The first set, Y1, was completed by Kinki Sharyo in October 2023. It was shown off to the public on 17 October 2023; Y2 would be completed a few days later. Testing commenced on 25 October 2023.
The sets entered service on 6 April 2024, with Y3 and Y4 on a Yakumo 8 service.
==Design==
The 273 series feature a somewhat streamlined design appearing similar to that of the existing 287 series sets and the 271 series sets. The sets feature a bronze livery with cream accents and iconography pertaining to the Yakumo service.
==Specifications==
The sets use an "on-board type natural tilting system with control" jointly developed by JR West, the Railway Technical Research Institute and Kawasaki Railcar Manufacturing. Traction motors are Hitachi VFI-HR2820Y silicon carbide MOSFET-based variable frequency drives; these are the same type as used on the 271 series sets. They are also equipped with the same four-note musical horn used on all of JR West's limited express trains since the introduction of the 681 series in 1991.

*The in-car chimes feature acoustic versions of songs performed by Japanese pop rock band Official Hige Dandism, whose members hail from Yonago and Matsue, cities along the lines the Yakumo service plies. Trains in the direction of Izumoshi play I Love... and trains in the direction of Okayama play Pretender.
