HO Scale Freelance Pennsylvania Railroad Layout

A freelance version of the Pennsylvania Railroad is the theme of this club sized HO masterpiece. Set in the summertime of the mid-1950's, this layout showcases the thriving steel, oil refining, logging, and coal mining industries, that were so prevalent in the period. Pennsylvania Railroad notable prototypes such as the Crestline roundhouse, and viaducts emulating PRR's Rockville Viaduct and the Erie RR Starrucca Viaduct, are featured historic highlights.

Fully programmable computer control complements the DCC and prototypical signal system providing for completely automatic train operation --- truly a delight for the high-tech savvy train enthusiast.

Engineered and built to the highest standards, exceeding museum quality, this one-of-a-kind model railroad layout more than achieves our client's vision.

Here's a second gallery of images from this layout, this time of the super-detailed industries and countryside.

Roundhouse - The round house is a replica of the Pennsylvania Railroad Roundhouse in Crestline, Ohio. Selective compression reduced the more than 180 degrees that the original has, but the character and unique style of this structure is still intact.

Steel Industry - This layout's extensive steel industry includes a customized Blast Furnace with glowing molten metal in the distribution troughs as well as other detailed support buildings.

Here’s what our client has to say . . . .

About three years ago I contracted with SMARTT to build a complete HO layout for my personal use. I looked at several layout makers and felt that SMARTT had the best technologies for doing my layout....

Planning the layout was a nice experience. Michael Hart had good ideas of how to fit a lot of action into the space....

We have wonderful scenery with mountains, a dock, a major city, and two small towns, one of which is a very detailed mining town. We have a lot of industry including a steel mill, a refinery, two coal mines, and more. We have a twelve stall roundhouse with a turntable and diesel refueling and repair areas and an extensive yard....

All of this may give you an idea of the extent of the layout but what is really wonderful about it is the great detail.... At my request, the entire layout is also controllable from a computer that can have multiple trains running at the same time with complete safety....The installation was very professional, with a team from SMARTT assembling the layout without issue despite its having traveled across the entire United States... The support after delivery has been excellent.

I doubt that any other company in America could handle a layout of such complexity with such excellent results."
