All Etched-Brass kit


The Lobato Trestle is a famous spot on the Cumbres & Toltec Scenic Railroad. It is north of
Chama in New Mexico and crosses Wolf Creek. The prototype Lobato structure includes six
plate girder spans and five bents. The tallest is about 75' with four stories.

The Cascade Creek Trestle is near Osier, Colorado and is also used by the Cumbres & Toltec
Scenic Railroad. The Cascade is longer with eight spans and seven bents; the center three
five stories at about 95' tall.

Both trestles are originally part of the Denver and Rio Grande Cumbres Pass Line between
Chama and Antonito. They were both designed by the same engineer and were produced at the
same time in the 1880s. The design has unique features. The girder spans are riveted together
into one solid length with no expansion connections, except at one end abutment. The
single-width bents are on pins so they can rotate slightly as the structure changes length in
varying temperatures. The taller bent legs taper in size to be widest in the middle, with
interesting curved-sided plates on the outside.

The model was an all-brass kit with resin stone footing and abutment castings. It was available
in components so you can assemble whatever bridge you desire.
Kit Info-

This grand kit has been retired. It was a grand project befitting a grand

WHERE'S THE COMPLETED JPS LOBATO TRESTLE?: I ran out of time to complete it for the display
base but I do plan on finishing the last girder and bent so I can make the entire bridge for display.

BRASS: The frets are beautiful. The bents are wonderful to build and hold- Bent C is GIGANTIC!
They are stunning! Soldering the bent parts makes them incredibly strong.

CASTINGS: A pair of simulated stone footings cast out of resin are included with each bent kit. They
have threaded inserts top and bottom for the shoe and mounting on the layout framework. Abutments
are available for anyone buying a girder span. They will make getting your girder spans to earth again

ASSEMBLY:  AC super glue can be used on the girder spans. For full strength the bent legs should
be soldered. I include patterns, instructions and etched brass fixtures for ease of assembly. The
instructions are downloadable on the
Instructions page. The video above shows how a typical beam is

PLANNING:  The bridge was made to the John Maxwell collection actual blueprint copies, and
whatever data I can find on the web and in print. There are detail drawings missing in the set, but by
scaling, interpolation and observation I did create the CAD drawings. The towers were tricky due to
the neat curving side plates- they cover the C-channel beam sides as they taper together to be closer
at the pin end than at the gusset end.

pivot as in the prototype.
Two cast resin footings come with every bent. Threaded inserts
are cast into the material for the shoe and a mounting screw.
The screws are included!

2) One flange/lacing part is soldered onto the sides (rivets facing down).
3) The three parts are now sturdy and aligned enough so the other
lacing part is soldered.
4) The overlay mini-frets are soldered in place with visual position cues.
5) The mini-frets are clipped off. Clean it up and that's it!
