The 12343/12344 Darjeeling Mail is one of the oldest running trains in India. It connects Kolkata with Haldibari This is a major train for KolkataâÂÂSiliguri route.
During the British period all connections to North Bengal were through East Bengal. From 1878, the railway route from Kolkata, then called Calcutta, to Siliguri was in two laps. The first lap was a long journey along the Eastern Bengal State Railway from Calcutta Station (later renamed Sealdah) to Damookdeah Ghat on the southern bank of the Padma River. The passengers would then avail a ferry across the river. The second lap of the journey was a metre-gauge line of the North Bengal Railway that linked Saraghat on the northern bank of the Padma to Siliguri.
The long Hardinge Bridge across the Padma came up in 1912. In 1916 the metre-gauge section north of the bridge was converted to broad gauge, and so the entire Calcutta â Siliguri route became broad-gauge. The route thus roughly ran: SealdahâÂÂRanaghatâÂÂBheramaraâÂÂHardinge BridgeâÂÂIswardiâÂÂSantaharâÂÂâÂÂParbatipurâÂÂNilphamariâÂÂHaldibariâÂÂJalpaiguriâÂÂSiliguri. The train ran on this route in pre-partition days. Even after the partition of India it ran on this route for some years. So before Partition: The train's pre-partition route was roughly: SealdahâÂÂRanaghatâÂÂBheramaraâÂÂHardinge BridgeâÂÂIswardiâÂÂSantaharâÂÂHiliâÂÂParbatipurâÂÂNilphamariâÂÂHaldibariâÂÂJalpaiguriâÂÂSiliguri.
With the partition of India in 1947, the major hurdle in connecting Kolkata and Siliguri was that there was no bridge across the Ganges in West Bengal or Bihar. A generally acceptable route to Siliguri was via Sahibganj loop to , then across the Ganges by ferry to Manihari Ghat on the other side, then to Kishanganj via Manihari, Katihar and Barsoi and finally through narrow gauge to Siliguri. In 1949 KishanganjâÂÂSiliguri section too was converted to metre gauge, thus making the entire route a uni-gauge one. On 26 January 1950 Sealdah Siliguri ( BG/MG) North Bank mail via Kishanganj was introduced. In 1964 it was renamed as Darjeeling mail. From 1947 to 1965, the Darjeeling Mail ran from Sealdah to Siliguri, passing through stations like Ranaghat, Gede, Darsana, Santahar, Parbatipur, Nilphamari, and Jalpaiguri, before crossing the border to reach the destination. This route was used after the partition before the Indo-Pakistani War of 1965 disrupted the passenger services. Even after the partition of India, the Darjeeling Mail initially continued to operate on a similar route. The Gede and Darsana stations in India and East Pakistan (now Bangladesh) served as custom checkpoints. The services were halted after the Indo-Pakistani War of 1965, severing the route.
From 1965-1971, Darjeeling Mail was made to run via 2 phases. The train used to depart Sealdah at 12.50 pm & reach at 23.30 pm crossing the Rajendra Setu spanning across the Ganges. Then it was a Meter Gauge journey of . The whole journey of used to take 19 hrs 15 mins. In 1970, - section was converted to Broad Gauge, speeding up the Darjeeling Mail & reduced time. station was constructed in 1960-1965 period on a greenfield site south of Siliguri Town.
In the early 1970s, when Farakka Barrage was being constructed, a more radical change was made. Indian Railways created a new broad-gauge rail link from Kolkata, and connected via , , joining the - section. The long Farakka Barrage carries a rail-cum-road bridge across the Ganges. The rail bridge was thrown open to the public in 1971, thereby linking the BarharwaâÂÂAzimganjâÂÂKatwa loop & Sahibganj loop to , Barsoi, Kishanganj, and other railway stations in North Bengal. Since then Darjeeling Mail has been using the HowrahâÂÂNew Jalpaiguri line. The train was numbered 3143 Up/3144 Down with Timings as follows: 3143 used to depart Sealdah at 19.15 pm, reaching at 06.30 am next morning & 3144 used to depart at 18.45 pm, reaching Sealdah at 06.00 am in next morning. This timings was prevalent until 2004, when Darjeeling Mail was renumbered as 2343/2344 & made Superfast by withdrawing some halts and journey time reduced. A slip train was introduced; consisting of a sleeper class and an AC-3 Tier coach. This service continued further to from . With the upgradation to LHB coaches, it was cancelled permanently and the entire train was extended till Haldibari. However this decision was met with apprehension as it was thought that it would reduce the importance of New Jalpaiguri station.
This train runs with 22 Linke-Hoffman Busch coaches. It has two dedicated rakes with primary maintenance at . It is an ISO 9001:2008 certified train.
