Athearn Genesis HO G31793 AC4400, Union Pacific #6837
Introduced by GE in 1993 and built until 2004, when it was replaced by the Evolution Series Tier II compliant model, the AC4400CW is a staple of modern railroading. 2,834 examples were built with many still plying the rails in their as-delivered configurations or as rebuilt variations. Many Class 1, regional, and foreign railroads purchased the AC4400CWs. Ownership spanned the North American Continent and with their long lives, have seen numerous paint scheme variations and ownership changes through the years. The AC4400CW went through a large number of changes during its production. Some are easily noticeable; early units being delivered with GE's Hi-Adhesion Trucks, while later units that had the option for newly developed GE Steerable Truck. Other details are smaller and takes a careful eye to see; the addition of a door stop, how the step wells are reinforced, or the number and positioning of panels and doors.
UP has always been on the forefront of new locomotive technology. When GE announced an AC version of their popular DC Dash 9 locomotives, UP ordered three (9997-9999) in 1994 for testing. Pleased with the results, UP would come back in 1996 and order 149 units (6738-6887). Through mergers with SP and CNW, UP became one of the largest owners of AC4400's with over 900 production units. A few received UP's newer "flag" scheme as depicted with UP 6700 which was originally UP 9997, UP's very first AC4400.

Preorder FAQs
How preorders work
Guarantee your reservation on any item marked with the red "Preorder item" flag, by paying just 10% down. Preorder items also display a date badge indicating the anticipated arrival.
We will email your invoice approximately 30-45 days before your preorder item lands at the warehouse. This interactive invoice will allow you to select your preferred shipping method, and pay the balance of your order, right online!
We'll ship you your preorder once your item arrives at our warehouse. Preorder fulfillments are queued in the order in which they were paid for.
Recently, our suppliers have made a major policy change and are no longer accepting product returns for non-paying end customers. After much consideration, we unfortunately must also change our policies to align with the realities our suppliers have created.
As our preorder offerings have grown, we’ve found that a large percentage of preorder reservations are canceled or left unpaid without notice. We pay our suppliers for every preorder item that arrives at our warehouse, so when a customer does not pay for their item, we are left no choice but to absorb that cost. We have tried our best to cope with the effects of this change; however, after more than a year of trying, we have found we cannot continue to do so.
We understand that this is an unwelcome change, and no one wants to pay earlier than necessary. However, this is unavoidable in order for us to be able to continue to offer the wide variety of preorder options you’re used to getting from Factory Direct Hobbies. We must now ask that customers pay a 10% good-faith down payment toward the price of their item. This non-refundable good-faith payment is applied to the price of the product, and the balance (plus shipping and any applicable taxes) will be invoiced approximately 30-45 days before the item is slated to arrive at our warehouse.
We thank you for your patience and understanding. If you have questions or would like further clarification, feel free to contact us through the gold chat bubble.
The good-faith down payment is not refundable if you choose to cancel your preorder or do not pay your invoice.
However, if a manufacturer cancels a project for which you have made a down payment, you will receive a refund for your down payment.
Yes. We know that paying ahead of time can be unnerving when delivery dates are distant, and not every project makes it to the production line. Rest assured that, in the event the manufacturer cancels your preorder project, you will be refunded your 10% down payment.
Hobbies should be fun, not stressful!
The manufacturing process involves many different moving parts, and this complexity often renders production timelines unpredictable. Therefore, some level of unpredictability in timing is inherent to preordering hobby products. Down payments are not refundable in cases of routine manufacturing, delivery, or other short-term delays.
However, we know it can be frustrating when a project gets delayed for many months. In the event a project is delayed more than 6 months beyond the delivery window originally estimated by the manufacturer, we will handle refunds of down payments on a case-by-case basis.
Friendly Reminder: Should you choose to cancel a preorder, it will no longer be reserved for you; in the event the item becomes available on our website, all customers will have equal access to purchase the item.
Nope! The policy is not retroactive: if you already made a preorder reservation before this policy update, you do not owe a down payment for that reservation. However, any future preorders you make will require the 10% good-faith down payment.
We make every effort to keep our website updated with information that reflects manufacturers' current estimated delivery schedules. To find the estimated delivery month of an item, you can visit our Preorder Section and use the filters to narrow down your selection.
However, we encourage you to directly visit the manufacturer's site for the most current delivery dates.
Approximately 30-45 days before your preorder items land at the warehouse, we'll email your invoice to you to pay in full. At this point, you'll be able to provide your shipping address and select your preferred shipping method.
Your item will be reserved for 7 days, beginning when your invoice is sent. After 7 days, your preorder will be canceled.
Recently, our suppliers have made a major policy change and are no longer accepting product returns for non-paying end customers. We have tried our best to absorb the effects of this change; however, after more than a year of trying, we have found we cannot continue to do so. After much consideration, we unfortunately must also change our policies to align with the realities our suppliers have created.
As a result, we must now ask that customers pay in full prior to the supplier finalizing shipment to FDH, about 30-45 days ahead of product arrival. This gives us the time we need to cancel with our suppliers any unpaid orders prior to shipment.
We understand that this is an unwelcome change and no one wants to pay earlier than necessary. However, this is unavoidable in order for us to be able to continue to offer the wide variety of preorder options you’re used to getting from Factory Direct Hobbies.
One silver lining is that this change will result in preorder items getting to your door even faster, as all payment processing will be well out of the way and the usual several day wait after product has arrived will be eliminated. We thank you for your patience and understanding. If you have questions or would like further clarification, feel free to contact us through the gold chat bubble.
Manufacturing schedules can sometimes be unpredictable. In the event your preorder item does not arrive at our warehouse within 60 days of your invoice payment, then you will have the option to cancel your preorder and receive a refund OR you may elect to continue waiting for the item.
Friendly Reminder: Should you choose to cancel a preorder, it will no longer be reserved for you; in the event the item becomes available on our website, all customers will have equal access to purchase the item.

For instance, with Athearn and Walthers, you can enter the part number into their websites and navigate to the item. Most of the time, the delivery date will be listed there. Broadway Limited has a published delivery schedule, as does Rapido.
Rewards and Preorders
Yes. Rewards can be used on both your 10% good-faith down payment and on the balance of your preorder at invoicing time.
Yes! Preorders are awarded reward dollars at the same 5% rate. You'll receive your reward within several days of paying the balance of your preorder invoice.
