Did the first through run to Constantinople really take 67 hours 35 minutes?
The figure is reported everywhere and was traced by nobody consulted for this pack to a timetable or a company document. It is repeated here as a reported number rather than a measured one, and the Journey treats the continuity it demonstrates — an all-rail run where there had been a ferry and a steamer — as the durable part of the claim.
Did a peace treaty oblige Austria to accept the rerouted service, and grant it a monopoly?
The claim appears in account after account without a treaty article ever being quoted, and the treaty text was not consulted for this pack. The Journey therefore asserts only what the record supports: the corridor became unavailable and the service went south instead.
Is the Blue Train running?
Genuinely unclear from open sources. The service was suspended in February 2022 over safety concerns on the network it runs across, and commercial listings show later departures with one end of the route moved; no operator statement confirming continuous service since the suspension was found. The Journey shows the gap rather than choosing a side of it.
Where do the corpus's own numbers disagree with themselves?
In three places that matter to the argument. The steepest worked grade on the Canadian main line is given as both 4.4 and 4.5 per cent; the tunnel under the Severomuysky Range is dated to both May and December 2003; and the Trans-Siberian's length is quoted by its operator at a figure the celebrated terminal marker does not match, with the number of time zones crossed reported as both seven and eight depending on what is being counted. None of the three is resolved, and none of them changes the mechanism they illustrate.
Is the charter train the same train?
A question of definition rather than of fact, and no source can settle it. The carriages are genuine; the company, the route, the crew and the purpose are not the same ones. The Journey states both halves and declines to adjudicate, because adjudicating would require a criterion the corpus does not hold.
Where, exactly, do these lines run?
Canonical knowledge locates the termini and the stations and declines to locate the routes: every corridor in this Journey is held as an object without geometry. That is the honest state of the model, not an oversight to be papered over — a Journey whose subject is alignment cannot currently draw one, and a line sketched between two pins would be an editorial invention wearing cartography. The absence is recorded here rather than worked around in the visual brief.
