Increasing the load capacity of freight wagon bodies is a key issue aimed at improving energy efficiency and competitiveness rail transport. This study presents for first time design body with increased proposes new changes to floor. To verify proposed solution, CAD models floor thicknesses ranging from 3 6 mm were developed, calculations performed von Mises stresses, resultant displacements, equivalent strains, safety factors each model. The factor structure has been by 5.2 times. results indicated that modified 1.6% 2.7%, depending on thickness, compared baseline construction thickness 7 mm. In addition effectively increasing wagon's load, modifications maintain structural integrity address mass considerations. Furthermore, these allow use standard carbon steel, which provides additional economic benefits. confirms thinner materials in can significantly enhance overall performance operational

Electric trains for reduction of fuel consumption and emissions from the freight transport in Jordan

PLoS ONE, Journal Year: 2025, Volume and Issue: 20(5), P. e0323121 - e0323121

Transport modes (trucks and diesel trains) used to move phosphate on the corridor connecting Shidiya mine Aqaba port in Jordan are causing pollutant emissions exceeding global average values. The study proposed use of electric trains compared their fuel consumption (FC) those existing transport an attempt regulate FC reduce from freight Jordan. For a more comprehensive view three modes, were evaluated various operating conditions relation varying speeds, loads, road gradients, curvatures. Results showed that vehicle types greatly impacted by increasing payloads speeds. On other hand, less affected road’s curvature its gradient. Electric can significantly CO 2 at 100% payload speed 60 km/h trucks trains. Also, would maintain N O acceptable levels. Regression analysis demonstrated significant negative correlations (R > 0.9) between with for vehicles. However, positive obtained speeds = 0.91) 0.77). offers insights into Jordan’s future strategies reducing pollution sector. Based findings study, drivers may preferably selected corridor. Besides, renewable energy sources could potentially further carbon rails.
