Abstract
This chapter deals with the main descriptive models of train resistance which can be interestingly applied in designing railway lines as well as managing and regulating traffic flows.

Notes
- 1.
The expression is similar to Lamm et al.’s, used in the road sector [3]: \({\text{f}} = 0.59 - 4.85 \cdot 10^{ - 3} \cdot {\text{V}} + 1.51 \cdot 10^{ - 5} \cdot {\text{V}}^{2}\)
By comparing the latter with Eq. (1.3) it is perfectly clear that, at the same speed, the adhesive-on-iron coefficient values are always lower than the corresponding on-road pavement values (asphalt pavements provide f values up to 0.85 with dry surface and to 0.50 with wet surface [3]).

Some remarkable examples are the 57 km long tunnel planned on the line Turin–Lyon, the 53.85 km long Seikan Tunnel in Japan, the over-50 km long Channel Tunnel etc.

The TGV in France set the record speed of 574.8 km/h; the same TGV technology in South Korea reached the speed of 330 km/h. The Eurostar in England set a national record of 334.7 km/h, while the Japanese Shinkansen reaches an operational speed of 320 km/h.

Brake systems can be classified as follows: shoe or block or tread brakes (the friction force is generated on the wheels by the pressure of metal or synthetic shoes) and disc brakes (the braking force is obtained by friction on steel discs, or cast iron, fixed to the axle of wheelsets) [10].
The braking force can be transmitted by using the following systems: air braking, electropneumatic braking, electromagnetic braking, electrodynamic braking [10].
- 5.
The braking distance is the key kinematic parameter for regulating train traffic (due to its vital importance in terms of safety) and, indirectly, it also affects the line capacity.
- 6.
tp corresponds to the driver’s perception/reaction time during the visual driving mode in railway and tramway lines.
- 7.
See, for instance, the braking model describes in the regulation “SCMT—Italian Train Protection System” published by Italian infrastructure manager of the railway network (RFI).
