           Thank you for purchasing this fine-scale model!  This bridge has been designed for easy 
assembly, exceptional durability, and ease of mounting.  Please feel free to contact us if you have 
any comments or concerns. Should an issue arise, spare parts are available for purchase.  

  Glue:  Any medium CA (super) glue.  (Super glue accelerator might also come in handy.)
  Hobby Knife:  A sharp hobby knife is imperative for cutting etched metal pieces from the          

frame in which they come.  (Be careful with sharp blades; use eye protection while cutting!)

  File:  To remove any burs left behind when the parts are cut from their etched frame.
  Paint:  Any flat black paint.  We recommend using an air brush to apply the paint.  It is easy to 

cover the small details with paint applied by brush.  Silver & White paint are needed as well.

  Toothless Pliers:  To aid in bending things such as the ladder supports, signal heads, etc.  

*Toothless pliers decrease the risk of causing damage to delicate, etched-metal parts.

  Toothpicks:  Come in handy when applying glue or small dabs of “touch-up” paint.

Cantilever Signal Bridge Instructions

Please read through all instructions before assembling and painting this structure.

         Modeled after a common Santa Fe protoype, this 
Cantilever  Signal  Bridge  has  been  in  use  all  over  the 
country for well over a half century.  Sturdy construction 
and a solid design has allowed these bridges to last into 
the new millennium.  The photos to the right are of the 
prototype bridge this kit is modeled after.  Replaced on 
the 1st of August, 2006, this relic survived long enough 
to see BNSF come to power over Santa Fe rails.

THE MODEL

THE MODEL

     Our HO Scale model of this interesting bridge is an 
exact scale replica of the prototype.  If you look closely, 
you will notice that everything down to the rivet detail is 
in  place!    Because  a  solid  model  starts  with  solid 
dimensions  and  drawings,  all  of  the  information  used 
was  taken  directly  from  the  prototype.    The  model 
photos to the right were taken at the same angle as the 
prototype photos to show how exact this model is.
