EMD F3B Locomotive Yellow and Gray UP 1406B Paragon4 (BLI7741)

EMD F3B Locomotive in Union Pacific yellow and gray, road number 1406B, featuring Paragon4 sound and control. This detailed cab-unit model brings the classic EMD F3B to life on a model railroad, offering authentic styling and operation for realistic layout running.

Designed for prototypical accuracy and reliable performance, it offers a prototypically painted and numbered finish, Mars Light and other lighting details, and numerous separately applied details such as grab irons and horns. Inside, a Paragon4 sound system with Rolling Thunder and an integrated dual-mode decoder with Back EMF deliver lifelike engine sounds and smooth slow-speed control in both DC and DCC. The ABS body rides on a die-cast chassis with all-wheel electrical pickup for strong pulling power, and two MicroTrains-compatible couplers help cars couple neatly. Compatible with Code 55, 70, and 80 rails, it requires a minimum 9-inch radius to navigate curves smoothly.
