The phases which come after phase 1?

Any context? I don't recognise those terms as meaning anything particular in Japanese N-gauge.
Takahachikawa - Japanese and other trains

Birmingham Knotmore Street - (ex) GWR mainline through the Midlands

I believe, but am not 100% sure, it relates to the type of alternating current. As its name implies, phase 2 has two voltage phases and phase 3 has 3... Phase 2 is the older of the two, so more likely to apply to the earlier electrics.

In terms of electrical supply, single phase supply is our domestic 240v/50Hz, but large electrically powered machines like capstan or centre lathes, milling machines and shaping machines etc use a 3 phase supply which is basically 3 x 240v/50Hz supplies which are "out of phase with each other  by 120 degrees whih gives a voltage of approximately 415v between phases -typically the machine will start on 2 phases but run on one. this system is more efficient than single phase, and is used widely by industry
