The total length of the line from P'yŏngyang to Busan is ; however, due to the
Korean Demilitarized Zone, regular operation is restricted to the section between P'yŏngyang and Kaesŏng.
22% of the line is laid with concrete sleepers, and it is the only railway line in North Korea capable of speeds of . The ruling grade is 11‰, the minimum curve radius is , and there are 99 bridges (total length ) and 13 tunnels (total length ).

–Kaesŏng railway line began in 1902.
After the outbreak of the
Russo-Japanese War it became imperative to transport freight north from Seoul to
Sinŭiju. Thus the
Kyŏngŭi Line was rapidly built, being opened by the
Temporary Military Railway for freight traffic on 5 November 1905 and to passengers on 3 April 1906. It was subsequently taken over by the
Chosen Government Railway (''Sentetsu'') on 1 September 1906. By 1 April 1908, when the "Ryuki" express train from Busan to Sinŭiju entered service, every station on the line was operational.

The railway bridge across the
Yalu River between Sinŭiju and

Trans-Siberian Railway. By the 1930s Sentetsu had put international trains between Korea and Manchuria, such as the ''Hikari'', ''Nozomi'', and ''Koa'' express trains, into service on this line.

The end of the
Korean War
The Korean War (25 June 1950 – 27 July 1953) was an armed conflict on the Korean Peninsula fought between North Korea (Democratic People's Republic of Korea; DPRK) and South Korea (Republic of Korea; ROK) and their allies. North Korea was s ...
established the current inner-Korean border, after which the North Korean section of the former Kyongŭi Line was split into two separate lines—the P'yŏngŭi Line from P'yŏngyang north to Sinŭiju, and the P'yŏngbu line from P'yŏngyang south to Kaesŏng,
P'anmun and the DMZ.
After having been closed since 1948, on 15 June 2000 an inter-Korean Joint Declaration was made, announcing the intention to reconnect the railways between North and South. On 31 July at the ministerial talks it was agreed to reopen the connection between the P'yŏngbu Line and the
Gyeongui Line from Kaesŏng to
Dorasan through the DMZ. Celebrations marking the reconnection were held on 14 June 2003 in North and South Korea. On 17 May 2007 the first train between North and South crossed the DMZ, carrying invited dignitaries from both sides of the inner-Korean border. The new stations at
Sonha and
P'anmun were opened at this time. The first scheduled freight train ran on 11 December 2007, carrying construction materials from Munsan in the South to Kaesong, and footwear and clothing on the return trip to the South.
The rebuilt station at
Pongdong between Sonha and P'anmun was also opened on this date. From then on, freight trains from the south to the Kaesŏng Industrial District were operated until 28 November 2008, when the North temporarily closed the line due to changes in the political situation. On 25 August 2009 it was closed once again, subsequently reopening on 1 December of that year. Tensions between North and South escalated again in 2013, leading to the closure of the border again on 4 May of that year, remaining closed until 16 September when it was reopened.
As of 10 February 2016 the border crossing is once again closed.
Services
Freight
Freight forwarded on the line is greatly dependent on the direction of movement. Between
Taedonggang and Hwangju, southbound freight traffic is 1.8 to 2 times greater than northbound, between Sariwŏn and P'yŏngsan, 56% of freight traffic is northbound, slightly higher than southbound.
Sariwŏn Ch'ŏngnyŏn station is the most important in freight traffic, having a large, automated freight sorting yard. Important freight yards are also in Chunghwa, Hwangju, P'yŏngsan, Sŏhŭng and Kaesŏng. Major commodities arriving at Sariwŏn include anthracite, fertilizer, steel, logs, stone, sand, and gravel. Freight arriving to Kaesŏng includes anthracite, wood, fertilizer, salt, steel, and cement, while outbound shipments from Kaesŏng are made up of

and iron ore towards the north,
and (when the border crossing is open) clothing, footwear and other products from the
Kaesong Industrial Complex.
The P'yŏngbu Line serves important industries such as the
Hwanghae Iron & Steel Complex, the
February 8 Cement Complex, the
Sariwŏn Textile Factory, the
Haeju Industrial Zone via the
Hwanghae Ch'ŏngnyŏn Line, as well as several mines, quarries, and other small- and medium-sized industries in
South Hwanghae province. Further, as it runs through one of North Korea's most important agricultural areas, grain, fertiliser, pesticides and agricultural machinery make up a large part of freight moved on the line.
Cement makes up a very significant portion of freight forwarded from points on the P'yŏngbu Line. Cement from the February 8 Cement Complex at
West Pongsan on the
Pongsan Branch accounts for up to 39% of northbound freight traffic on the Pongsan–Sariwŏn section, a portion of this being destined for the port at Haeju for export, via the Hwanghae Ch'ŏngnyŏn Line. Ore and minerals also make up a notable portion of freight moved on the line, destined for the Hwanghae Iron & Steel Complex at
Changch'ŏlli on the Songrim Line, and for the
Ch'ŏllima Steel Complex and the
Namp'o Smelting Complex on the P'yŏngnam Line. This includes minerals from sources on the P'yŏngbu Line, such as limestone from

Pig iron, steel and other ferrous metals from the Hwanghae Iron & Steel Complex make up up to 22% of northbound freight traffic from Hwangju towards P'yŏngyang. There is no northbound coal traffic, yet coal accounts for the majority of southbound freight, due to the lack of coal deposits in South and

provinces. Coal forwarded from the
P'yŏngdŏk Line is brought onto the P'yŏngbu Line at Taedonggang, from where some goes to P'yŏngyang, but the bulk moves south; in particular, up to 76% of southbound freight between Taedonggang and Hwangju is coal, most of it destined for the Hwanghae Iron & Steel Complex.
Passenger
The P'yŏngbu Line is connected to several other lines in P'yŏngyang, and, as such, is responsible for a portion of passenger traffic from Kaesŏng and South Hwanghae province. However, passenger traffic on the P'yŏngbu Line is relatively light in comparison to the high volumes of passenger movements on the P'yŏngŭi and
P'yŏngra Lines. Hwangju, Sŏhŭng,
Kŭmch'ŏn, and P'yŏngsan stations are transfer points for passengers from
Yŏnt'an,
Rinsan and
T'osan counties, which have no railways.
The following passenger trains are known to operate on the North Korean section of the line:
* Express trains 15-16/17-18, operating between
Haeju Ch'ŏngnyŏn and
Manp'o Ch'ŏngnyŏn, run on this line between Sariwŏn and P'yŏngyang.
* Semi-express trains 104-107/108-111, operating between Haeju Ch'ŏngnyŏn and
Hyesan Ch'ŏngnyŏn, run on this line between Sariwŏn and P'yŏngyang.
* Semi-express trains 119-122/120-121, operating between
Sinch'ŏn and
Ch'ŏngjin Ch'ŏngnyŏn, run on this line between Sariwŏn and P'yŏngyang.

* Local trains 202-203-204/205-206-207, operating between
Hamhŭng and
Sariwŏn Ch'ŏngnyŏn, run on this line between P'yŏngyang and Sariwŏn.
* Local trains 219/220, operating between
Taedonggang and
Ch'ŏlgwang, run on this line between Taedonggang and Sariwŏn.

, run on this line between Sariwŏn and P'yŏngyang.
In the 1980s there was a long-distance local train running between Sariwŏn Ch'ŏngnyŏn and
Hamhŭng, which ran from Sariwŏn to P'yŏngsan via the P'yŏngbu Line, from P'yŏngsan to
Sep'o Ch'ŏngnyŏn via the Ch'ŏngnyŏn Ichŏn Line, from Sep'o to
Kowŏn via the
Kangwŏn Line, and from Kowŏn to Hamhng via the P'yŏngra Line—a distance of .
The current status of this service is not known.
There is only one express train operating on this line, due to a far greater demand for short-distance commuter service than long-distance travel.
