The experiments dealing with the mechanical and physical properties of the track components such as fasteners, pads,… are performed in this laboratory. The geometrical parameters of track can also be measured by portable devices. A set of some commonly used machines used during the construction or maintenance of the railroad superstructure and also a welding apparatus (thermit method) are located for educational purposes.
The brief description of the laboratory apparatus are as follows:
1- Track Master
It measures the geometrical parameters of tracks such as gauge, grade, torsion, super elevation,… .

2- Joint Gap Recorder
It measures the joint gaps (the gaps between the rails) and the temperature of rails using sensors and a spot thermometer respectively.

3- Mini-Prof Apparatus
The apparatus is used to measure and calculate the wear of rails, wheels, brakes and switches profiles.

4- Sleeper Holding Test Apparatus
Equipped with a compressive jack and a data logger, the lateral resistance of sleepers can be measured.
