The position of the train station depicted in the 1905 Ordnance Survey (this track dates to 1909) indicates that the east half of this track section is not accurate. A detailed trackplan dating from the 1960s also indicates this to be so.

Both plans are available on the County Donegal Railway.

An aerial photograph of the area dating from the 1970s is available on the 1st Battalion Duke of Edinburgh's Royal Regiment website.

Since Strabane is currently in the United Kingdom, and this node represents the flag of the Republic of Ireland, there is a potential for this item to be misinterpreted if we set flag:type = national.

Given the prospect of a rendering engine displaying a Union Flag beside a Republican monument, I believe flag:type = governmental might be a better choice here.
