This article presents a business history of the Barranquilla Railway and Pier Company (BRPC) and its impact on Colombia’s Caribbean region. It explores the company’s operations, profitability, shareholders, infrastructure development, and competition with other coastal railways for insights into the role of foreign capital in regional growth. The BRPC’s railway and port infrastructure connected the coastal city of Barranquilla with the Colombian interior, allowing the city to supplant Cartagena as the country’s principal international port. Statistical analysis reveals the railway’s remarkable profitability, which attracted transnational investors, who consolidated majority control. The company’s ability to leverage engineering expertise and capital underscored its strategic significance, yet its interests centered on protecting its transport monopoly. The railway’s lack of visibility in London and information asymmetries shaped investor perceptions. Extending the pier demonstrated BRPC’s role in accommodating rising export volumes during Colombia’s “despegue cafetero.” However, the railway faced obsolescence, as the government opened the obstructing Bocas de Ceniza sandbank and pursued railway nationalization. The railway’s redundancy, demographic shifts, and rise of Buenaventura underscore its eventual decline. This paper reveals the complex dynamics between foreign capital, infrastructure, and trade monopolies in shaping uneven development. It highlights the BRPC’s overlooked yet fundamental role in Colombia’s export economy and Barranquilla’s ascendancy.

Introduction: Globally, railway transport is increasing steadily. Despite the adoption of diverse safety systems, major railway incidents continue to occur. Higher speeds and increased passenger traffic are factors that influence the risk of mass-casualty incidents and make railway crashes a reality that merits extensive planning and training.

Methods: Data on railway disasters were obtained from the Centre for Research on the Epidemiology of Disasters (CRED), which maintains the Emergency Events Database (EM-DAT). This descriptive study consists of 529 railway disasters (≥10 killed and/or ≥100 non- fatally injured) from 1910 through 2009.

Results: The number of railway disasters, people killed, and non-fatally injured, has increased throughout the last hundred years—particularly during the last four decades (1970–2009), when 88% of all disasters occurred. In the mid-20th century, a shift occurred, resulting in more people being non-fatally injured than fatally injured. During 1970–2009, 74% of all railway disasters occurred in Asia, Africa, and South and Central America, combined. The remaining 26% occurred in Europe, North America, and Oceania, combined. Since 1980, railway disasters have increased, especially in Asia and Africa, while Europe has had a decrease in railway disasters. The number killed per disaster (1970–2009) was highest in Africa (n = 55), followed by South and Central America (n = 47), and Asia (n = 44). The rate was lowest in North America (n = 10) and Europe (n = 29). On average, the number of non-fatal injuries per disaster was two to three times the number of fatalities, however, in the African countries (except South Africa) the relation was closer to 1:1, which correlates to the relation found in more developed countries during the mid-20th century. The total losses (non-fatally and fatally injured) per disaster has shown a slight decreasing trend.

Conclusions: Despite extensive crash avoidance and injury reduction safety systems, railway crashes occur on all continents, indicating that this type of incident must be accounted for in disaster planning and training. Better developed safety, crashworthiness, and rescue resources in North America and Europe may be factors explaining why the number of crashes and losses has stabilized and why the average number of people killed per disaster is lowest on these continents.

The purpose of this study is to determine how the viewing distance affects the pass/fail results of the CN Lantern (CNLan). The CNLan is a color vision test designed for the railway industry. It presents 15 triplets of colored lights that could be any combination of red, green and yellow. The test was viewed from 4.6 m and 2.3 m. Sixty-seven color-defectives participated in the first part of the study. Sixty-six percent of the subjects repeated the experiment 10 days later. There was a significant (P < 0.05) decrease in the mean number of errors from 7.6 to 4.3 as the distance decreased. There was also a corresponding increase in the percentage of subjects who passed from 9.0% at 4.6 m to 20.9% at the 2.3 m viewing distance. None of the subjects who passed at the longer distance failed at the shorter distance. The replication results were statistically identical to the first session (P > 0.05). Decreasing the CNLan viewing distance by 50% does decrease the number of errors and increase the pass rate. This indicates that some color-defectives could work in the railway yards where the sighting distances for the signal lights are shorter than on the main track.

Sécurité – Performance – Endurance – Fiabilité, sont les mots clés du vocabulaire des concepteurs et des personnels de maintenance des matériels ferroviaires. La préservation de l'environnement s'inscrit comme un nouvel élément à ces préoccupations dans le cadre du développement durable.Bien que les performances des moyens de simulations numériques ne cessent de progresser, la SNCF continue de s'appuyer sur l'expérimentation pour vérifier et valider les dispositions prises par les bureaux d'étude. L'Agence d'Essai Ferroviaire, à travers les compétences de son personnel et de ses moyens d'essais, contribue activement à la maîtrise de ces objectifs.
