Hiller Enterprises LLC™ manufactures and sells Open Car Loads of Fun™ including:

Pipe Loads of Fun™. These Loads are my signature product line for all scales, makes and models of model train gondolas, flatcars and flatbed vehicles. For details about my Pipe Loads “click” on Pipe Loads Modeling. If you don’t find your particular Pipe Load on our website, contact me with your specifics. We will every effort to accommodate your needs.

Pipe Loads of Fun™ are designed and built to 1) look like the real thing; 2) represent a specific prototypical pipe diameter (See NOTE 1 below.); and, 3) fit within the inside length (IL), inside width (IW) and inside height (H) of your gondolas, flatcars, bulkhead flatcars and flatbed vehicles.

Pipe Loads of Fun™ are labeled according to model railroading scales (Z, N, HO, S, O, G) or some other scale fraction; length in “real” 1 to 1 inches; pipe coating color; the number of pipe layers e.g. 4+4+4+3 is a 44443 pipe load (See NOTE 2 below.); and whether “yellow rope” pipe separators are required. Yellow plastic rope is typically used to protect each piece of coated pipe.

Z-scale Pipe Loads of Fun™ are priced at $10.00 per inch in length for all pipe layer configurations.
See NOTE 3 below.

N-scale Pipe Loads of Fun™ are priced at $2.00 per inch in length for 21 and 22 pipe layers, $2.50 for 321 or 332 pipe layers, or noted otherwise within this website.
See NOTE 3 below.

HO-scale Pipe Loads of Fun™ are priced at $2.50 per inch in length for the 44443 layer configuration. If an HO 321 pipe load with 1/2 inch actual pipe diameter is desired the price is $2.00 per inch.
See NOTE 3 below.

S- and O-scale Pipe Loads of Fun™ are built with 1/2 inch “actual” diameter pipe, are priced at $2.00 per inch for 321 or 332 pipe loads, $2.50 per inch for 443 pipe loads, and $2.50 per inch for 4443 pipe loads.
See NOTE 3 below.

NOTE 1. Pipe diameter. I generally use plastic pipe of a diameter that looks good for a particular scale and closely resembles a generally used prototype diameter. However, I will try to match your specifications. If I cant’, I will contact you to discuss your options.

NOTE 2. Pipe layer nomenclature. A 4+4+4+3 or 4443 pipe layer designation or similar numbering means from the bottom of the pipe load to the top there are 3 layers of 4 pipes, and 1 layer of 3 pipes. This scheme is used throughout my pipe loads product line. For more or fewer pipe layers, contact me for pricing.

NOTE 3. Pipe Length and Pricing. The longest pipe length I can build for you without “welding” additional pipe is 14" actual length. The price of my pipe loads is calculated by multiplying the length of a particular layer configuration, e.g. 4443 by the cost per inch of pipe load. I round the length to the nearest whole inch with the 1/2 inch mark as the break point between rounding lower or rounding higher. EXAMPLE. A 7 and 3/8 inch length is considered 7 inches for pricing. A 7.5 inch to an 8 inch load is considered an 8 inch long load for pricing.

Mineral and Material Loads of Fun™. These noteworthy Loads of Fun model coal, iron ore, ballast, gravel and wood chips for all makes and models of model train flatcars, gondolas and hoppers, and vehicles hauling these products.

If you don’t find your particular mineral or material load, contact me with your specifics. We will every effort to accommodate your needs. We can build-to-order car and vehicle loads representing metal shapes and scraps, wood, and other material “shapes” based on your model railroad and trucking needs.

Liquid Storage Tanks The Liquid Storage Tanks product line models storage tanks for fuels, oil, water, and other liquids.

Special Purpose Cars™. This product line features model train flatcars modified to haul Lego® style building block creations; and model train stock- and boxcars equipped with QSIndustries® Live Action Sound Units™(LASU’s).
