HO EMD SD45 Locomotive ATSF 5621 Bookend Scheme with Paragon 4 (BLI7931)

HO-scale Santa Fe 5621 EMD SD45 locomotive in the Bookend scheme, equipped with Paragon 4 sound and control for authentic operation on DC or DCC layouts. This model reproduces EMD’s 645E3 20‑cylinder engine rated at 3,600 horsepower, bringing the power and presence of the original freight hauler to your layout.

Paragon 4 delivers true-to-life sound and control with Rolling Thunder and includes a dual‑mode decoder with back EMF for smooth slow-speed performance. The locomotive features an all‑wheel pickup, ABS body with a die‑cast chassis for maximum tractive effort, prototypical paint schemes and road numbers, and many separately applied details such as handrails, grab irons, horn, bell, wipers, and etched grills. Two metal Kadee‑compatible couplers are included, it runs on Code 70/83/100 track, and it requires an 18-inch minimum radius for reliable operation.
