HO Scale Union Pacific CA-11a Caboose with Lights & Sound, UP #25843. This highly detailed, ready-to-run HO model reproduces the CA-11a caboose with a true-to-life interior and exterior. Inside you’ll find a fully detailed interior—conductor’s desk, stove, sink, bathroom, radio stand, and more—while the exterior features see-through end platforms, etched window screens, and precision painting for prototypical realism. LED lighting lights the interior and walkway areas, and a built-in DCC decoder powers the lighting and sound for authentic operation on a model railroad.

Designed for HO layouts, this caboose uses an on-board DCC decoder by NCE, enabling operation in both DCC and analog power with lighting control in DCC. LED interior and marker lights offer long-life illumination with adjustable brightness, and all functions are NMRA-compatible in DCC mode. The car rides on machined metal wheels with RP25 contours and a weighted underframe for smooth, reliable performance on common tracks, and it comes fully assembled and ready to run with prototypical painting. It supports multiple UP road numbers and has a minimum recommended radius of 18 inches; sound-equipped versions provide authentic horn or whistle, clickety-clack with optional wheel-flat sounds, brake noises, emergency brake cues, and handbrake actions when used with compatible decoders.
