We are a group of 5 over sixty y.o. adults planning on traveling by train from Copenhagen to Stockholm and back. Staying in Stockholm five nights. Wish to take high speed train, round trip in mid-August. Suggestions, guidance and cost-saving insights appreciated. Thank you.
The train is operated by Sweden and all the various price options are displayed at www.sj.se. Senior discounts start from age 65. You'll notice a big difference between fare choices: "Non-rebookable" (cheapest, and often sell out in advance), "Rebookable" (these are the rates shown on our train-fare map online), and "Refundable" (much higher fare, but unrestricted).
This info about track work is on the site, too:
The Swedish Transport Administration will be working on the tracks south of Stockholm Central station from 24 June to 18 August, inclusive. Instead of Stockholm Central, south-bound trains will stop and depart from Stockholm Södra or Flemingsberg, with some exceptions. The station information in the timetable and on your ticket is always correct.
What does this mean for you?
You will need to change to an SL commuter train to travel to or from Stockholm Central. The cost of the SL ticket is included in the price [when booked to Stockholm Central station].
Do you already have an SL ticket [or pass]?
At the next stage, choose Stockholm Södra or Flemingsberg as your destination or starting point and use your SL ticket to complete your journey.
