The 735 series (735系) is an electric multiple unit (EMU) train type built in 2010 and operated by Hokkaido Railway Company (JR Hokkaido) on suburban services in the Sapporo area in Hokkaido, Japan, since May 2012.

Design

The 735 series is intended as an experimental type to evaluate the suitability of aluminium-body rolling stock in the cold climate of Hokkaido. The cab ends however use steel construction. They were tested in winter conditions from 2010 to 2011.[2]

The 735 series sets are able to run in multiple with 721 series, 731 series, and 733 series suburban EMUs, but not with KiHa 201 series DMUs.[2][3]

History

Set A-101 on display at Sapporo Depot Open Day, August 2010

Two 3-car sets were delivered from the Hitachi factory in Yamaguchi Prefecture in March 2010.[4]

The sets first entered revenue-earning service on 1 May 2012.[5]

gollark: Any opinions on my theory of what's going on with the pricing? Basically, I said that if extra dragons are introduced to the total but not the rest of the system (golds, whatever else), then rarer stuff's ratios will be affected more than common stuff, so the gold pricing goes crazy and nebulae stay the same.

gollark: 3.

gollark: My theory of what's up, copied from the forum thread:If many new eggs are being introduced to the system, then that will most affect the stuff which is rarest, by making it rarer by comparison, but commons will stay the same. As for why it happened now? Weekly updates, possibly.Example:Imagine there are 200 dragons, 5 of which are golds.The ratio of golds to total dragons is now 5:200 = 1:40. If the target ratio is 1:50 then prices will be higher to compensate.Now imagine there are an extra 200 dragons added, none of which are golds.The ratio would then be 5:400 = 1:80. Then, assuming the same target, prices will drop.This is of course simplified, and the ratios may not work like this, but this matches observed behavior pretty well.

gollark: That why was rhetorical.

gollark: As I said on the forums:```That makes sense. If many new eggs are being introduced to the system, then that will most affect the stuff which is rarest, by making it rarer by comparison, but commons will stay the same. As for why it happened now? Weekly updates, possibly.```
