Tanjong Pagar railway station (Malay: Stesen Keretapi Tanjong Pagar; Chinese: 丹戎巴葛火车总站; Tamil: தஞ்சோங் பகார் ரயில் நிலையம்), also called Singapore railway station (Malay: Stesen Keretapi Singapura; Chinese: 新加坡火车站; Tamil: சிங்கப்பூர் ரயில் நிலையம்) or Keppel Road railway station, is a former railway station located at 30 Keppel Road in Singapore. The station was the southern terminus of the network operated by Keretapi Tanah Melayu (KTM), the main railway operator in Malaysia, until 30 June 2011 when the station ceased operations with relocation of the KTM station to Woodlands Train Checkpoint. The land on which the station and the KTM railway tracks stood was originally owned by KTM and over which Malaysia had partial sovereignty. This arrangement lasted until 30 June 2011, when rail service to Tanjong Pagar was ended and the land reverted to Singapore.
 The main building of the railway station was gazetted as a national monument on 9 April 2011, completing one of the objectives of the new Points of Agreement between Malaysia and Singapore.
 It will be a future site for Cantonment MRT station, one of the stations for Circle MRT line Stage 6.
 Before the Johor-Singapore Causeway across the Straits of Johor was built, the railway in Singapore was limited to the island. The construction of the causeway began in 1919, and it was opened to goods trains on 17 September 1923 and to passenger trains on 1 October 1923. Previously, passengers and goods, particularly to service the transportation of tin and rubber industry in Malaya were transferred at Woodlands to a ferry to Johor Bahru and the connecting train on the peninsula. Tanjong Pagar railway station was completed on 3 May 1932 and officially opened by Sir Cecil Clementi. It was around for 79 years before it ceased operations on 1 July 2011 to be reserved as the Singapore Railway Museum.
 In 1859, Captain William Cloughton built the first dry dock. With the emergence of steamships and growth of shipping industry, Tanjong Pagar Dock Company was formed in 1864, building wharves in the area. The area grew and was known as the ‘New Harbour’ shortly before being renamed as Keppel Harbour in 1900 by Acting Governor, Sir Alexander Swettenham.
 Subsequently, with much political demands, plans to build a railway through Singapore, primarily to service the New Harbour, came underway in 1899 and the Singapore-Kranji Railway was completed in 1903. Between 1906 & 1907, the line was extended southwards from the terminus station at Tank Road to Tanjong Pagar and the wharves. It was eventually disused due to noise complaints by nearby residents.
 KTM used to run six daily KTM Intercity trains between Singapore and Kuala Lumpur, the capital city of Malaysia.  It also ran several other trains between Singapore and other parts of Peninsular Malaysia, such as Kelantan state in the northeast. It also operated a shuttle service between Johor Bahru and Singapore for commuters. Until 30 June 2011, the stops in Singapore were at Woodlands (for immigration clearance by Singapore Immigration and disembarkation of passengers travelling from Malaysia) and Tanjong Pagar (embarkation and disembarkation).  Since 1 July 2011, the only stop in Singapore is at Woodlands.
 Tanjong Pagar and Outram Park MRT stations are approximately 1 km from the Tanjong Pagar railway station.
 Upon arriving in TPRS's main hall, the first thing that many encounter was Habib Railway Book Store and Money Changer. Having been part of the station scenery since 1936, it is certainly one institution that many regular passengers would patronize before embarking on their trip. Opened in 1936, the shop was where Mohd Seeni, a proprietor, used to work before taking over in 1958. He was the longest serving staff in the station.
 The station canteen, renowned for its tasty and affordable food, had been established since 1984 by the Hasan brothers. One of the hawkers, Mohammed Ali Latif, had been selling Nasi Bryani in the canteen for 8 years before its closure. He started his business from scratch, selling 20-30 servings a day to about 300 a day. On the last day of business in the station, his food was sold out within 2 hours with more than 700 loyal customers coming to support him.
 TPRS was also home to Mr Dennis Lim, whose father used to run the station hotel for over 60 years since 1932. The 34-rooms hotel was housed in the upper floors of the station and its service was known to be equivalent to Raffles Hotel during its peak, to the extent that many dignitaries like the Malaysian royalties frequent the hotel. Having lived and worked there most of his life, Lim also mentioned that the hotel exuded a strong colonial ambience, with massive rooms having high ceilings and restaurant's waiters dressed in white with silver buttons.
 The popularity of the hotel began declining in the 1970s due to physical deterioration of the station building and the negligence of maintenance by the Malayan Railway authorities. Roof leakage caused much ceiling moisture damage and plumbing problems became a prevalent issue. All these led the decline in the hotel's appeal and business spiraled downwards.
 Following an agreement between the governments of Malaysia and Singapore on 24 May 2010, railway operations at the station ceased from 1 July 2011. The conserved building may be integrated with future developments on the site or turned into a museum. KTM's southern terminus was relocated to the Woodlands Train Checkpoint.
 The closure of the line between Tanjong Pagar and the Woodlands checkpoint was something that had been considered for some 20 years with the intention made clear through the Malaysia–Singapore Points of Agreement of 1990, though the exact details could not be agreed upon until the agreement was signed between the two countries in 2010. Though supported by some, the closure was opposed and lamented by others as representing a great loss of Singapore's heritage and of a key public transportation facility. At the time of closure, Singapore had already built 180 km of domestic MRT and LRT lines combined.
 In 2015, the Urban Redevelopment Authority (URA) proposed that the station be converted into multi-functional community space as part of the revamp of the Rail Corridor stretching from Kranji to Tanjong Pagar. A request for design plan was announced. The winning proposal for Tanjong Pagar Railway Station includes a public park in front of the station named Station Green, and an integrated entrance to an underground MRT station.  Facilities such as an auditorium and art gallery would be added, and the Railway Corridor would become a linear park that would be nearly ten times longer than New York's High Line. The redevelopment is set to take place over 20 years.
 The building is in a richly ornamented Art Deco style. On its exterior are four reliefs of white marble, allegories of Agriculture, Industry, Commerce and Transport. They are works by Angiolo Vannetti [it], a sculptor from Florence, Italy.
 The hall has a barrel vault roof.
 Inside the main public hall, the walls bear panels with scenes depicting economic activities that were historically significant in Malaya: rice planting, rubber tapping, shipping activities, bullock cart transport, copra growing and tin mining.
 These panels and the original floor slabs were manufactured locally, using rubber to deaden noise.
 The two long platforms were capable of accommodating the longest mail trains, covered by umbrella reinforced concrete roofs.
 The status of the railway station was disputed between the governments of Malaysia and Singapore.
 When Singapore left Malaysia in 1965, there was no border control between the two countries. When the two countries established border controls, both the Malaysian and Singaporean Customs, Immigration and Quarantine (CIQ) officers were stationed at Tanjong Pagar for  clearance of railway passengers. Road travellers clear immigration at the Malaysian side of the causeway and Woodlands, Singapore upon entry to Singapore. In this case, the CIQ of both countries are separated.
 In 1990, Malaysia and Singapore signed an agreement concerning Tanjong Pagar railway station. Malaysia agreed to relocate the station to Bukit Timah, thus freeing up land for development. In return, Singapore agreed that railway land at Tanjong Pagar would be handed over to a private limited company for joint development, with equity split 60% to Malaysia and 40% to Singapore. However, the parties interpreted the agreement in very different ways. Singapore insisted that the agreement took immediate effect but Malaysia argued that the agreement would come into effect only after it decided to move the station.
 Since 1992 KTM has worked with Singapore on re-aligning its railway tracks at Woodlands, where Singapore built a new immigration checkpoint to replace the old checkpoint, with facilities to carry out train passengers' immigration clearance instead of at Tanjong Pagar. In 1993, Malaysia responded that it would transfer its CIQ operations to the new Woodlands checkpoint.
 However, in June 1997 Malaysia stated that the Malaysia-Singapore Points of Agreement of 1990 would come into effect only after it decided to relocate Tanjong Pagar station. Malaysia also informed Singapore that it had changed its mind and decided not to co-locate its CIQ with Singapore's at Woodlands Train Checkpoint (WTCP) but to remain at Tanjong Pagar. In April 1998, Singapore informed Malaysia that it would be moving its CIQ operations to Woodlands while Malaysia would have to move its CIQ out of Singapore from 1 August 1998. Malaysia requested, instead, that space be made available at the WTCP, as an interim arrangement, for Malaysian Immigration officials to operate from there and thereby overcome the problem of sequence of exit and entry stampings by Singapore and Malaysia immigration authorities.
 According to a press release from the Ministry of Home Affairs of Singapore dated 24 July 1998:
 However, Malaysia refused to have its immigration clearance on the platform: it insisted that Malaysian Immigration should be inside the building at WTCP. If this was not possible, it said that Malaysian Immigration would remain at Tanjong Pagar. Singapore argued that Malaysia's decision to locate its Immigration Control Post in Singapore was not in compliance with Malaysia's own law. Under Malaysian law, it is Johor Bahru railway station, not Tanjong Pagar, that is gazetted as an Immigration Control Post for persons travelling by train from Singapore to Malaysia. Singapore also pointed out that this was confirmed by the endorsement on the passports of passengers boarding the train at Tanjong Pagar, which showed:
 "MALAYSIA IMMIGRATION
JOHOR BAHRU
SOCIAL/BUSINESS VISIT PASS
Reg. 11. Imm. Regs 63
[Date]"
Permitted to enter and remain in West Malaysia and Sabah for one month from the date shown above"
 On 1 August 1998, Singaporean Immigration ceased operations in Tanjong Pagar and moved to WTCP, while Malaysian Immigration continued operating in Tanjong Pagar. Malaysia decided not to endorse the passports of outgoing rail passengers from Singapore and promised to provide legal arguments to show that Malaysia's CIQ had the legal right to stay at Tanjong Pagar.
 The immigration clearance procedure which resulted from the impasse until 1 July 2011 was:
 In early 2007, news of a Singaporean woman being jailed for failing to have her passport stamped when entering Malaysia threw the spotlight on the unusual clearance procedures. The Ministry of Foreign Affairs reminded Singaporeans that their passports would not be stamped when departing for Malaysia by train, instead stamping a disembarkation card, which had to be retained until departure from Malaysia. The entry records were also entered into a computer system. Even then, this arrangement continued to present problems for some commuters.
 On 24 May 2010, a meeting between Malaysian Prime Minister Najib Razak and his Singaporean counterpart Lee Hsien Loong in Singapore resolved the relocation issue. In a joint statement after the meeting, they announced that KTM would move out of Tanjong Pagar railway station and establish a station at the Woodlands Train Checkpoint (WTCP), making it the southern terminus of the Malaysian rail network, from 1 July 2011. Malaysia would also relocate its customs, immigration and quarantine facilities from Tanjong Pagar to the WTCP, enabling an integrated border crossing facility between Malaysia and Singapore.
 Singapore agreed to ensure a connecting bus service between WTCP and a nearby MRT station, and for the National Heritage Board to preserve the station building in any development of the area. Bukit Timah railway station building at Blackmore Drive can also be conserved.
 Both sides agreed to create a consortium called M-S Pte Ltd, of which 60% equity is owned by Malaysia's Khazanah Nasional Berhad and 40% by Singapore's Temasek Holdings Ltd. The company will be vested with three parcels of land in Tanjong Pagar, Kranji and Woodlands and three additional pieces of land in Bukit Timah (Lot 76-2 Mk 16, Lot 249 Mk 4 and Lot 32-10 Mk 16) in exchange for the return of KTM railway land to Singapore, which was swapped with the Marina One and dUO plots of land, which is located at Marina Bay and Bugis areas in Singapore, in a bid to boost the financial growth in the central business district, and the nearest MRT stations to their M-S Pte Ltd ownage of the land are Marina Bay and Bugis.
 Both sides also agreed to the building of a rapid transit link between Johor Bahru and Singapore to enhance connectivity across the Causeway. After the completion of the link, the KTM terminus may be relocated to Johor.
 The last train out of Tanjong Pagar was driven by Sultan Ibrahim Ismail of Johor, whose grandfather, Ismail of Johor, had opened the causeway between Singapore and Malaya in 1923. The Sultan had to learn how to drive a train before he was able to perform this task, receiving training from KTM. Two drivers accompanied him to ensure safety.
