Leslie RS-4T Horn (SL-4T reproduction with RS Power Chambers!)

The SL4T was used by Amtrak before the K5LA and very few real ones exist today. I temporarily converted my RS5T into an SL4T replica, composed of bells 31, 37, 48, and 55 (basically a S3K with a 55 bell added). A very unique and recognizable sound for sure.
The 48 bell in this example was 3d printed.
