Rapido (40030) | EMD GP40 | Union Pacific #3001 (1996+) Mother | DC/Silent [Optional DCC Upgrade] | HO Scale

🚂 Take It From “Runs” to “Runs Like It Should”

Put OJ to work and upgrade this unit to DCC — or go all-in with DCC & Sound.

With the DCC & Sound upgrade, OJ professionally installs the decoder and programs it with sounds tailored specifically to this locomotive using the ESU LokProgrammer. 

And listen — I don’t casually toss around the word professional (especially where OJ is concerned 😉)… but when it comes to decoder installs and programming depth? He absolutely earns it.

Prefer to handle the install and programming yourself? You can select the decoder-only option below and take it from there.

To add one of the options below, add the product to your cart and choose your option.  Please allow 1-3 processing days for installation/programming. 

Rapido is proud to announce the EMD GP40 locomotive! The GP40 series was considered the gold standard of four-axle locomotives, with over 1,000 examples built for 30 different railroads in North America. EMD began production in late 1965 with an order for the New York Central. The final locomotive in the series would roll off of the line in 1971 for the Chesapeake & Ohio, number 3794. In between that time period, the Penn Central would amass the largest fleet with the Baltimore & Ohio coming in at a close second. After 1971, production would continue on with the successor: the GP40-2.

Our first run will bring you many never-produced-in-plastic variations, such as: nose and Gyra/Mars lights, stepwell variations, Canadian versions and slugs. The Missouri-Kansas-Texas (MKT) Railroad converted a heavily-damaged GP40 into a unique one-of-a-kind road slug, number 501. We will be producing 501 in both MKT and Union Pacific - complete with a working motor. Every DCC/Sound locomotive comes with the Mo-Power capacitor, which will end most interruptions to track power. A win for all!
