In 1918, Czechoslovak State Railways were established and the station got a new again.
With the independence of Czechoslovakia, the Olomouc-Prague railway became the main railway line in the country.
The station was no longer able to serve the increasing traffic demand.
At that time there was still the original reception building from 1845 and the newer building from 1871.
The Ministry of Railways had decided that the Kolín railway station will have to be rebuilt to meet the new conditions.

A brand new building was designed by architect Vladimír Weiss in a functionalist style but it was built between 1938 and 1939, way after the previous plan, by Dr. ing.
V. Mrha company at the place of the original reception building from 1845.
In connection with the construction of the new reception building, a reception building from 1871 was also laid down and the platforms were built on an extra-level island.
The reception building consisted of an oblong one-storey building, which was situated along the tracks.
The larger part of the reception building occupied the central courtyard, which served as a departure hall.
From there, the stair led to the subway to the island platforms.
The symbol of the new railway station was the emblem of the winged wheel in which the clock was placed, it was located above the entrance.

In the summer of 1939, the station was used for long-distance national connections from Prague Wilson Station (central) to Havlíčkův Brod and Jihlava.
Connections with regular departure from Kolín at 8:27 and at 17:15 arrived in Jihlava at 10:24 and at 19:07.
On the territory of the Protectorate of Bohemia and Moravia, the state railway company Českomoravské dráhy was established during the Second World War, but changing the owner was just formal.
On 18 April 1945 Kolín station was bombed by Allied air forces.
The freight and marshalling yards were most damaged during the raid.
Bombing also damaged adjacent factories, especially "Draslovka" (Kalliwerke A.G.), which produced Zyklon B for usage in concentration camps.
The station post office was also damaged.

After the end of World War II, the administration of the station passed to Czechoslovak State Railways.
In the morning of 16 May 1945 President Edvard Beneš was welcomed there, as he used a train on his return from the war exile in Great Britain.
At the head of the special train No.
11.554 was locomotive 387.032, the train was accompanied by an armored train "Moscow".
By special timetable, the train stopped in Kolín with a ten-minute stop.
The expected train stay at the station was from 12:28 to 12:38 (the timetable was probably not met).
In addition, the armored train was accompanied by a condensing locomotive Class 52.
The war-damaged railway station is documented in a film that Česká televize ("Czech Television") announced on the "Hledání ztraceného času" program.
At 5 o'clock in the afternoon of 15 June 1945, a freight train collided with a passenger one in the station, 27 people died.
 
Station Kolín has not maintained its status of significance for decades.
The proof may be a timetable issued one year after the end of the war.
Ex 31 "Ostravan" passed the station.
Also during World War II several connections from Prague to Ostrava and Brno were passing through the station.
In the 1944 timetable, this was the case for express trains No.
3 and 9.

In the 1960s, the station was equipped with Soviet-type signal light.
In the intermediate station section from Kolín to Pardubice, the automatic block signaling was already operating, also in the opposite section to Prague.
On the other hand, a semi-automatic block with track gates was still used in the stations in direction to Havlíčkův Brod.
Here the automatic block signaling appeared only in the 1980s.
The symbol of the 1960s was Pannonia Express, which traveled through the station from Berlin to Sofia via Kutna Hora.
In 1969/1970 it was Ex 56 "Pannonia" and Ex 57 "Pannonia".
Trains were obligatory to be booked and had relatively high speeds at that time.
They were already driven by electric locomotives E 499.1.
