HO RF-16 Sharknose Locomotive A/B SP 5550 / 5570 Black Widow (BLI7708)

The RF-16 Sharknose Locomotive A/B Set in SP 5550/5570, Black Widow is an HO-scale diesel that captures Baldwin’s iconic Sharknose in a faithful ABA pairing. The set includes a powered A-unit with Paragon4 Sound and a dual‑mode DC/DCC decoder, plus an unpowered B-unit with a lightweight frame to form the classic A-B lash-up. An extra powered A-unit is available for this scheme to expand the roster.

Designed for authentic operation on HO layouts, this model delivers prototypical detail and performance: Paragon4 sound with Rolling Thunder and a dual-mode decoder with Back EMF for smooth slow-speed control on DC or DCC; a precision drive for heavy towing and steady low-speed operation; all-wheel electrical pickup; ABS body with a die-cast chassis for maximum tractive effort; prototypically accurate paint schemes and road numbers; many separately applied details such as grab irons, horns, and a bell; prototypical lighting and Baldwin Sharknose sounds; MicroTrains-compatible couplers; compatibility with HO track codes 55, 70 and 80; and a minimum operating radius of 18 inches.
