AB  - Comprehensive dataset of permafrost temperature along the Nenlin Railway (6 boreholes), covering the period from August 1, 2023 to March 25, 2024. The data was automatically collected through the thermistor temperature chain (developed by the State Key Laboratory of Cryosphere Science and Frozen Soil Engineering, with a measurement accuracy of ± 0.05 ℃) deployed on the site, and recorded by the CR3000 data acquisition instrument and the TRM128 deep hole temperature measurement expansion board, with a collection frequency of 2h/time. The raw observation data is calculated on a daily basis to generate daily scale data, forming a dataset. This dataset can be used for thermal characteristics analysis of frozen soil along pipelines, monitoring of frozen soil environments, research on engineering thermal disturbances, and related research on frozen soil disasters and environmental science.  The spatial location information of the table data is as follows:  Longitude (Tuqiang Water Plant North: 122.7209; Amur: 123.212653; Changying: 123.304782; Xiufeng: 124.587094; Taiyanggou: 124.281266; 94 kilometers: 124.184812)  Latitude (Tuqiang Water Plant North: 52.94937; Amur: 52.838268; Changying: 52.875296 Xiufeng: 52.498947; Taiyanggou: 51.310306; 94 kilometers: 51.149723)
