# Okayama Electric Tramway

Okayama Electric Tramway (岡山電気軌道, Okayama Denki Kidō) is a transportation company in Okayama City, Chūgoku, Japan. The private company operates tram lines and bus lines. The company and its lines are officially abbreviated as Okaden (岡電).
The company was founded in 1910, while its first tram line was opened in 1912. This is one of the few Japanese railway operators that maintained their original corporation names from the foundation in Meiji Period. The company is a core member of the Ryōbi Group, another core member being Ryōbi Bus. From October 1, 2006, together with Ryōbi Bus and Okayama bus company Shimotsui Dentetsu (Shimoden), Okaden introduced Hareca, a smart card ticketing system accepted on trams and buses in Okayama. Okaden also accepts the 10 Nationwide IC Cards including PiTaPa, ICOCA, Suica and PASMO.

## Chuggington Tram

Since March 16, 2019, Okaden operates a special tramcar representing Wilson and Brewster from Chuggington, a British animated children's TV series. Built by Niigata Transys in 2018, it is a low-floor articulated tram based on the design of the existing Okaden 9200 series trams [ja] but with extensive modifications including fibreglass mouldings to represent a locomotive, raised driving position & driver's windows and custom-shaped windows. Designed by Eiji Mitooka, the tram interior features childrens play areas, special seating and video screens playing Chuggington videos.
Chuggington Tram operates similar to a tourist train, with tickets sold for a designated tour travelling on both of the company's tram lines. Ticket information is available at the Okaden Chuggington Tram website. Tours commence at Okayama Ekimae (tram stop opposite Okayama Station) and terminate at Higashiyama, adjacent to the Okaden Chuggington Museum. Tour tickets include entry to Okaden Chuggington Museum as well as a 1-day tram pass.
Chuggington Tram only operates specified tours (as well as being available for private hire) and does not operate any regular passenger services.

They also operate limousine buses linking Okayama Station and Okayama Airport, while Okaden Express is a highway bus that links Okayama and Kōbe / Kōbe Airport.

## Supporting other railway lines

Okaden is known for its active stance to try to support other railway lines, when their operators announced to close them. So far, they have considered supporting 4 lines of Meitetsu (Gifu City Line, Ibi Line, Minomachi Line, and Tagami Line), as well as Hitachi Dentetsu Line, Nankai Kishigawa Line, and Hokkaidō Chihoku Kōgen Railway Furusato Ginga Line. Among them, they succeeded to support Kishigawa Line, now operated by Wakayama Electric Railroad, their subsidiary company.
