The Archive Department has encountered a number of difficulties when attempting to establish the dates and locations of Arthur Cecil Ingram's travels.
However, the latest recovered fragment has presented us with an entirely new problem.
We cannot establish the century.
Indeed, we are having some difficulty establishing whether the century has been invented yet.
An Unusual Railway Junction
The fragment is labelled Bedrock Junction, a location that does not appear in any of our railway directories, historical timetables or geographical records.
Arthur's accompanying notes describe a surprisingly busy railway operation, complete with passengers, railway staff and what appears to be a functioning station.
At first glance, the arrangements are not entirely unfamiliar.
There are platforms, a recognisable system of passenger handling and a degree of organisation that would not be out of place on a conventional railway.
It is the motive power that presents the difficulty.
There is no steam locomotive.
There is no diesel engine.
There is certainly no evidence of electrical traction.
Instead, the railway appears to depend upon a rather large prehistoric creature.
A Question of Motive Power
We have examined the recovered illustration several times.
Our initial assumption was that the creature represented an elaborate piece of railway machinery, perhaps constructed for a public exhibition.
Closer inspection has made that explanation increasingly difficult to maintain.
The creature appears to be alive.
More remarkably, the railway staff seem entirely unconcerned by this arrangement.
Arthur, naturally, appears to have taken a professional interest in the engineering implications.
We suspect that his first concern was not the presence of a prehistoric animal, but whether the resulting service could maintain a reliable timetable.
There is no indication of a coal supply, water tower or locomotive shed.
We have, however, noticed what may be a substantial feeding area beside the station.
This raises several questions concerning operating costs, maintenance arrangements and the likely responsibilities of the shed foreman.
We have decided not to investigate the last of these too closely.
The Bedrock Railway Company
One of the more curious aspects of the fragment is the apparent confidence with which the railway is operated.
Passengers seem perfectly accustomed to the service, while the station staff conduct their duties with the reassuring indifference found amongst railway employees in almost every period Arthur has visited.
Whatever its unconventional methods, this appears to be an established transport system rather than an experiment.
That observation is perhaps the most troubling of all.
Arthur has previously encountered railways at the beginning of their development, during their greatest achievements and even in futures we cannot yet recognise.
But this fragment suggests something rather different.
A railway existing before the machinery upon which railways are generally understood to depend.
A Remark in the Margin
Amongst Arthur's notes, one observation has attracted particular attention:
"Perhaps not every railway requires rails."
It is an interesting suggestion, although one that we suspect would provoke considerable discussion at a meeting of the Institution of Civil Engineers.
We have also been unable to determine how Arthur arrived at Bedrock Junction, or how he subsequently departed.
As with several earlier fragments, the beginning and end of his visit are missing.
There is no ticket, no timetable and no record of a connecting service.
Only the illustration, the journal fragment and Arthur's characteristically calm observations of an otherwise impossible situation.
The Archivist's Conclusion
We have provisionally classified Bedrock Junction as an unidentified railway operation of uncertain date.
Whether it represents an ancient civilisation, an elaborate fabrication or another of Arthur's inexplicable journeys remains unresolved.
For now, we are left with a simple observation.
Wherever Arthur travels, and whatever form the railway happens to take, someone invariably finds a way to operate a passenger service.
We can only hope that Bedrock Junction has fewer delays than its modern counterparts.
