Recognized for both its reliability and elegant appearance, the K4 Pacific was emblematic of the power and style of the mighty Pennsylvania Railroad in the early-to-mid 20th century. Developed primarily for passenger service, the K4 could frequently be found leading some of the most celebrated trains of the era, such as the Broadway Limited and the Spirit of St. Louis, while also proving more than capable when handling freight. In 1987, preserved K4 #1361 was designated as the state locomotive of Pennsylvania, adding a further dimension of historical significance to the class. The Bachmann Spectrum® HO scale K4 returns to our line, now featuring TCS WOWSound® DCC with CD-quality, 16-bit 44,100Hz audio, a Keep-Alive® device for smooth running through brief power interruptions or over dirty track, and Audio Assist® for easy programming without CVs.
