This applied study sought to measure the impact of the Haramain High-Speed Train (HHST) project on the neighborhoods of Tibah municipality by studying the impact of the train on land prices and urban growth in the years 2016, 2018, and 2021. Through the use of various statistical methods and a geographic information system (GIS) program, the study found that the average price of land near the train remained low, while the middle and far distant land prices experienced a gradual rise. The study also examined the rate of urban growth in the study area, demonstrating that the lands near the train were characterized by a high rate of growth, while the middle and far distant lands from the train line demonstrated a low level of urban growth. Further research should explore the economic effect of the train in Jeddah city in terms of employment and commercial investments as well as the economic impact of the railway system on the city's growth and expansion.
