The Navigation Menus-

To search the site, use the top and bottom navigation menus.  Put your mouse arrow over the name of the page you would like to visit and click that page name.  To search for parts, use the left navigation menu.  Put your mouse arrow over the name of the general category of manufacturer and it will bring up a subcategory list (if applicable).  Then put your mouse arrow over the subcategory you would like to search on and click.

Parts Searches-

There are three different ways to search for parts on the OTTP website. The results of the search will give you a list of part numbers, their descriptions, what car/loco/accessory it fits, a price, a picture of the item so you can check to see if that is what you are looking for and an “add to cart button” (see Online ordering and “my shopping cart”). (We are working hard on getting pictures for all our parts, but at present, we only have pictures for about 4000 of them. We are updating as quickly as we can.)

The first is by part number. For this type of search you would have to know the part number (or at least a partial part number) for what you are looking for. To perform a “search by part number”, click on the link for your desired manufacturer on the left menu bar. The search page that results will default to “search by part number”.  If you would prefer to search by fits or by description, there are blue links to those search pages below the white text box.  Click in the white box and type your part number (or partial part number). Click the gray “Search Button” to the right of the white box. The search will return a list of all the part numbers that contain everything you typed in, so if you aren’t completely sure of your part number, it is better to only put in partial numbers.

The second is a search by what we call “fits”. This means, enter the number of the car, loco, or accessory you are trying to find parts for, and the search results will contain all the parts we have for that particular piece. To perform a “search by fits”, click on the link for your desired manufacturer on the left menu bar.  Choose the “Search by FITS” link under the white text box.  This takes you to the "search by fits" page for your manufacturer.  Click in the white box and type your car, loco, or accessory number (check the faq’s page for help on how to figure out what it is that you have). Click the gray “Search Button” to the right of the white box. The search will return a list of all the part numbers that fit the car, loco, or accessory you typed in.

The third is by description of the part you are looking for. To perform a “search by description”, click on the link for your desired manufacturer on the left menu bar. Choose the “Search by Description”  link under the white text box.  This takes you to the "search by description" page for your manufacturer. Click in the white box and type your description. Click the gray “Search Button” to the right of the white box. The search will return a list of all the part numbers that description column or fits column contain everything you typed in, the more specific you are in your descriptions, the narrower your search results set will be.  Remember, every word you type in the description you search on has to be in our description of a part in order for it to be returned to you.  Please leave out unnecessary words such as "the, in, a, etc..." because we might not have them in our descriptions.

Online ordering and “my shopping cart”:

When you search for parts through the “Parts Search” pages (see parts searches), the resulting set of part numbers will have an “add to cart button” next to each individual part. If you find the part you are looking for and you want to place an order, type in the quantity you desire and press the “add to cart” button. The default quantity is 1. To view the items in your shopping cart, visit the Shopping Cart page by clicking on the "Shopping Cart" link in the left menu bar. To change the quantity of any item in your shopping cart, just put the corrected quantity in the white box after the price columns and press the update button.  When you are done shopping, go to the shopping cart page, look over your order and press the checkout button, it will guide you through the ordering process

FAQ’s page:

If all else fails and you still have a question, visit the FAQ’s page by clicking on it in the top or bottom menu bars. It has the answers to many hobby-specific questions as well as more detailed information on ordering from OTTP offline.
