It surrounds the İstasyon Square together with the Central Post Office, Türk Telekom and TCDD Regional Headquarters.

In 1903, the Ottoman Government contracted Istanbul-Baghdad section of the Berlin-Baghdad Railway project to Germany.

It is a 3-storey structure with wide eaves and a triangular roof and has a U-plan in which the open area faces the square.

The middle section, which connects to the square through three sharp arch gates, is the main hall with a high ceiling and includes the waiting room, ticket offices and the information desk.

There are administrative offices at the north part of the east and the west wing of the building, facing platform I.

The four-piece window sets, facing Platform I at the upper section of the north walls, provide plenty of light to the hall.

The bands that are covered with geometric forms, stretching in east-west direction on the ceiling, also add quality to the space.

The eaves surrounding the roof on the upper portion of the wings and the twin window sets beneath, the wide eaves extending all along above the arch gates at the middle section of the elegantly designed building front show that horizontal elements are dominant in the architecture.

The ground and the first floor windows in front of the wings are in vertical frame, forming a more stable image.

Also like the front side, three-slice twin blind arches are placed above the doors and the windows of the offices that are at the same level with platform I.

Ornaments of the building are the two large rectangular-shaped faience panels on both sides of the main entrance, the faiences that placed in a niche at the section of the west and east wings that face the main entrance and the geometric shaped ornaments at the bottom surface of the eaves.

Track IV has no platform, therefore serves freight trains that cross the station without stopping.
