Spotlight Review

"Smart buy for an addition."
Tim (North Las Vegas)
This kit makes a great addition to the main kit and it easily allows you to add as many stalls as you want. it does require some fine detailing like painting parts before assembly to get that weathered look, but it is pretty solid without going too crazy.

  • The Magic and Mystique of Engine Servicing Facilities If there is a land where dragons live, it lies before you. Ahead, dozens of the black monsters rest after battle. The sulfur smells of coal smoke, hot iron and oil mix in the hazy morning air.
  • Not long ago, places like Peach Creek, Cheyenne, Roanoke, Portland, Altoona and Spencer shook with the passage of these giants. Whether it was massive articulateds, Queens of the high-speed passenger fleet, or lowly yard goats, steam locos of every size were refueled, repaired and made ready for their next assignment.
  • And now, the glory days are back, in an all-new collection of seven HO Scale Cornerstone Series(R) kits from Walthers. Bigger Is Better Finally, you can model the support structures that your biggest and best engines deserve quickly, affordably and easily with Walthers kits.
  • Typical American designs, they'll handle any loco from 0-4-0 to 4-8-8-4 and each fits in a space that makes them practical for any layout.
  • Easy to Add or Expand Whether modernizing your existing terminal or building a new one, these kits are the perfect starting point.
  • They're easily mixed and matched with other structures to capture the look of newer facilities built to speed operations.
  • A Central Theme for Limited Space Like the feel of big-time railroading but think you don't have room? Think again!
  • Now you can easily design and build a realistic terminal with plenty of action in a small area. It's a perfect way to display and operate your favorite locos too. And, a facility like this provides nonstop work for one or two operators.
  • Adaptable to Many Eras Don't model the steam-era? Don't worry, you CAN use these structures on your layout!
  • Facilities like these appeared in the 1920s and some are still in use today. A Complete Series of Kits This complete series of Cornerstone Series kits brings you everything you need to model ALL of the facilities you'd find in a typical engine service terminal.
  • Authentic American Prototype
  • Holds Engines up to 125 Scale Feet Long
  • Includes Stall for Bigger Engines up to 145 Scale Feet Long
  • Modular Design-Easily Expanded to a Full Circle
  • Compact 10-Degree Stall Spacing
  • Fine Window Details
  • Floor Inspection Pits
  • Decal Signs Included
  • Though engines started getting bigger early in the 20th century, no one could foresee the monsters that were in regular service by the 1940s. These locos required equally large servicing areas, so some roads simply added and extended a few roundhouse stalls to handle them. This conversion kit adds three matching stalls to the Modern Roundhouse (933-2900, sold separately). With additional kits, you can expand the basic building to any size your railroad requires. Engines up to 125' fit easily inside, and parts to build a single 145' long stall are included - big enough to hold a Big Boy.
  • Measures 17-3/4 (20-1/8 with extended stall) x 16 x 5-1/2" 44.3 (50.3) x 40 x 13.7cm.
