Abstract
From the second half of the 19th century, two technologies were implemented in Portugal: photography and railways. In this article, I analyze the interactions between them in eight photographic albums portraying the construction, operation, and various aspects of Portuguese railways built between 1872 and 1914: Minho, Douro, Beira Alta (two albums), Tua, Salamanca to the Portuguese border, North (construction of the Maria Pia bridge) and Vouga. Drawing from the bibliography on railway photography, I revisit some of its conclusions and add reflections on photography as an instrument of territorial appropriation and creation of landscapes, as well as on its material dimension, as a vehicle that transports ideology, representations, and places. I contribute to the debate on the use of photography as a primary source (and not just as an illustrative accessory) and to a call for greater use of this source in historiographical analysis, especially in the field of transport history.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
