I wouldnt think you can get away with putting a patten on that

You could not patent the concept of whistle steam. However, the arrangement of the items to impart whistle steam to a hobby locomotive could hypothetically patented. However, such a patent would be a "method" patent. This would encompass things such as how big the exhaust hole is, how long is the tubing to deliver the smoke, where the drive fan is, where the electronics are. Method patents are the weakest. If someone accomplishes the same task but with a different method, for instance different length of tubing then that would be a work around of a method patent and would not infringe. However, it has to be shown that the different length in tubing is important to the function and not just to get by a patent. If MTH came up with a different method, then that would not infringe on Lionel.

@WBC is right on the money.  An old-time word that applies here is "apparatus".

The apparatus for generating whistle steam can be patented, but may not have been.  A major requirement is that the design and operation of this proposed apparatus must not be obvious to someone skilled in the trade beforehand.

Is the means for generating whistle steam obvious (and therefore not novel)?  Or is it a true innovation?

How are electronic boards installed / serviced with a diecast Vandy tender?

Front or back side removable ends?

Reconfigured to a longer thinner footprint to fit into a long narrow opening?

For the 3rd Rail models I've worked on, the skinny "chassis" on the bottom is removed and the board are typically mounted on that.  The opening is just wide enough for the 1.25" width boards to fit through.  There are some models where you have to stuff them in one end, not remembering which maker right now.  I believe Lionel has at least one that the front end comes off to access the boards, and there's a magnetic door on top to access the battery.

Beth,

   I was excited to see new steam right up to the moment I didn't see 2-rail offerings. 

    I assume they're not offering 2-rail because they don't expect to get enough orders.   I sent them an email asking them about future 2-rail offerings a while ago but got no response.   Have you asked them to build any 2 real versions?  Is there any hope they will make 2-rail steam in the future? 

I already bought the PRR 2-rail version from you in PS3 but would like the C&O 2-rail version in PS3 also.
