[BUG] Issue with trailers

[sergjack2015]

On multi-trailer vehicles, such as trams, the mod only works properly on the first trailer. On other trailers I either can't add text entries, or the camera doesnt mode to that trailer, or the text parameter doesn't work (for example, LastStopLine shows either the "default" stop name even when it's been renamed, or doesnt show anything at all).

To reproduce:
Create tram line. Have 2 terminal stops and rename them. Set text on 1st trailer to show destination. Do the same for last trailer. Observe error.

What is shown on 1st trailer:

What is shown on last trailer when approaching default terminus:

What is shown on last trailer when the vehicle has passed the default terminus:
