Consider the following statements regarding the Fog Pass Devices: It i...
The correct answer is option 'A' - Statement 1 only.

Explanation:
Fog Pass Devices are not GPS based navigation devices, and they are not limited to diesel locomotives only. Let's understand each statement in detail:

1. It is a GPS based navigation device which provides on-board real-time information.
Fog Pass Devices are not GPS based navigation devices. Instead, they are specialized devices used in the railway industry to improve visibility during foggy weather conditions. These devices use ultrasound technology to detect the presence of obstacles such as other trains, vehicles, or any obstructions on the railway tracks. They provide real-time information about the presence of obstacles and help the train operators make informed decisions while driving in foggy conditions. Therefore, statement 1 is incorrect.

2. It is suitable only to diesel locomotives.
Fog Pass Devices are not limited to diesel locomotives only. They can be used with both diesel and electric locomotives. The purpose of using Fog Pass Devices is to enhance safety and visibility during foggy weather conditions, regardless of the type of locomotive. Therefore, statement 2 is incorrect.

In conclusion, neither statement 1 nor statement 2 is correct.
