[Bug]Train cars and locomotives desync, shake, and snap back after coupling/uncoupling #141

Description

@Vlados-Ddos

When playing multiplayer, my friend is the host and I join his session as a client.

A reproducible issue occurs when we are operating the same train from opposite ends. For example, the host is driving a locomotive at the front of the train, while I am driving a locomotive at the rear.

The issue can happen during normal shunting operations. When the host couples or uncouples locomotives and/or wagons, the train may become visually desynchronized on the client side.

From the client's perspective, the wagons and locomotives may start shaking heavily. In some cases, they appear to be dragged along behind the host's train for a short distance, even though they have already been uncoupled. After that, they suddenly snap or teleport back to the position where they were originally uncoupled.

The issue can occur both when uncoupling and when coupling vehicles together.

In my experience, the shaking and desynchronization are usually temporary and resolve themselves after approximately 10–15 seconds.

Additionally, there is another, less common issue where locomotives may occasionally start shaking while driving even without any coupling or uncoupling actions, although this happens much less frequently.

This issue was observed from the perspective of the client connected to the host's session.
