Packing matrix summary
Per person: four outfit sets total, of which one is worn in transit and three packed; seven underwear and seven sock pairs, with one each in the personal bag; one sleep set; one warm layer; one forecast-dependent wind/rain layer; maximum two shoe pairs including worn. The day-3 laundry supports four outfit sets but does not reduce the stated daily underwear/socks count. One delayed-laundry buffer is the personal-bag change already counted, not an extra duplicate. Total across four: 16 outfit sets including four worn, 28 underwear, 28 sock pairs, four sleep sets, four warm layers, up to four rain layers after verification, and up to eight shoe pairs including four worn.
Personal bags: each traveler owns phone, charger, identity documents required after official verification, valuables, and one underwear/sock change. A additionally owns camera, lens and only the verified-access battery arrangement. G keeps cane and medicine accessible; medicine details are not in the shared list. Named adult B provisionally holds C's verified documents, subject to family confirmation. The shared day bag carries only duplicated-use items such as water bottles or tissues after local and transport rules are checked; do not pack four separate shared sets.
Suitcase A/B and suitcase C/G: remaining clothing, sleep sets, nonessential toiletries, second shoes and confirmed rain layers. Allocate by weighed item, not assumption; each suitcase must be measured after packing against the household 15 kg target. No weight total is claimed because item weights are absent. Bedding/towels are excluded because lodging confirms them. Detergent is buy-at-destination or bring only after lodging and security verification.
Verification queue: seven days before, official rail/operator and security sources for bag size/count, liquids, spare batteries, tripod, scissors, snacks, medicine and document rules; official route source for identity documents; lodging for detergent and appliance operation; meteorological source at seven days and 48 hours for temperature, wind and rain-layer choice. Record source, date and implication. Unknown rules mean hold, not pack.
Checks: photograph bag contents only if travelers consent; label two suitcases and four personal bags without exposing sensitive data; charge devices; download confirmations; weigh suitcases; verify six-night lodging and day-3 laundry; confirm cane/medicine/electronics remain accessible. At transfers count 2 suitcases + 4 personal bags + 1 folded/day bag. At lodging inspect laundry and replan if unavailable. Before return repeat rule, weather, item and bag counts; separate dirty/wet items, retrieve chargers, medicine, documents and valuables, and reconcile purchases with available space.
