This sound project is a collaboration between Wickness Models and Marks Trains, the project incorporates all the benefits of our RealDrive Projects and includes specialist ambient soundscape of your choice. This model shows many of the features including multiple playable horns on a single function, the soundscape and the two separate soundtracks for Electric and Diesel running. Here is the Sound Bulletin with extended instructions on prototypical lighting https://wicknessmodels.co.uk/wp/wp-content/uploads/2017/09/RealDrive-73-Airport.pdf
