Grass tracks are mostly installed for new tram tracks because they help to reduce noise and vibration, as well as provide a more aesthetically pleasing environment in urban areas. Trams typically operate at lower speeds and have lighter loads compared to the German railway, making grass tracks a suitable and sustainable option for tram infrastructure. On the other hand, normal tracks are used for the German railway due to the heavier loads and higher speeds of the trains, requiring a more robust and durable track system to ensure safety and efficiency. **

Without seeing the specific tracks in question, it is difficult to definitively say whether they are animal tracks or not. However, animal tracks typically have distinct patterns and shapes that can be identified with the help of a field guide or expert. Look for characteristics such as the number of toes, claw marks, and the overall shape of the track to determine if they are indeed animal tracks. If in doubt, it's best to consult with a wildlife expert or tracker for a more accurate identification. **
