The E1 series (E1系) was a high-speed Shinkansen train type operated by East Japan Railway Company (JR East) in Japan from July 1994 until September 2012. They were the first double-deck trains built for Japan's Shinkansen. They were generally, along with their fellow double-deck class the E4 series, known by the marketing name "Max" (Multi-Amenity eXpress).^[1] The fleet was withdrawn from regular service on 28 September 2012.^[2]

Originally intended to be classified as 600 series,^[3] the E1 series trains were introduced specifically to relieve overcrowding on services used by commuters on the Tohoku Shinkansen and Joetsu Shinkansen.

E1 series sets were used on the following services.^[4]

• Joetsu Shinkansen
  • Max Asahi (July 1994 – November 2002)
  • Max Tanigawa
  • Max Toki (until 28 September 2012)
• Tohoku Shinkansen
  • Max Nasuno (until December 1999)
  • Max Yamabiko (July 1994 – December 1999)

The fleet of 12-car sets, numbered M1 to M6, were formed as follows, with car 1 at the Tokyo end.^[5]

Cars 6 and 10 were each equipped with a PS201 scissors-type pantograph.^[5]

The E1 series was the first revenue-earning shinkansen to feature 3+3 abreast seating in standard class for increased seating capacity. The upper deck saloons of non-reserved cars 1 to 4 were arranged 3+3 with no individual armrests, and did not recline. The lower decks of these cars, and the reserved-seating saloons in cars 5 to 12 had regular 2+3 seating. The Green car saloons on the upper decks of cars 9 to 11 had 2+2 seating. The trains had a total seating capacity of 1,235 passengers.^[9]

The first E1 series set, M1, was delivered to Sendai Depot on 3 March 1994, sporting "DDS E1" logos (DDS standing for double-deck shinkansen).^[10] ローカル鉄道途中下車の旅 The first two E1 series sets delivered entered revenue-earning service on the Tohoku Shinkansen on 15 July 1994, with the original "DDS" logos replaced by "Max" logos.^[3] The original livery was "sky grey" on the upper body side and "silver grey" on the lower body side, separated by a "peacock green" stripe.^[5]

From 4 December 1999, all six trainsets were transferred from Sendai Depot to Niigata Depot, with operations limited to use on Joetsu Shinkansen Max Asahi and Max Tanigawa services only.^[5]

Between 1 December 2001 and 31 March 2002, the E1 series fleet was adorned with "Alpen Super Express" logos as part of JR East's "JR + Snow" promotional campaign.^[3]

From mid August 2012 until the fleet's final withdrawal on 28 September, the remaining three sets had a second toki crested ibis added to their logos to celebrate the rare hatching of ibis chicks in the wild.^[13]
