Summary of Contents for GMC Rapido F9B

  • Page 2 F7B/F9B LOCOMOTIVE PRODUCT GUIDELINES Thank you for purchasing this Rapido Trains F7B/F9B locomotive. Much like the good neighbours of the FP7 and FP9A shared their own manual, we’re making the F7B and F9B share a manual as well. Why? Well because they’re largely the same, save for a porthole here and maybe a ladder there.

    PROTOTYPE NOTES Many will ask “Do we really need another B-unit?” or “What makes this one different from the others?” Well, the General Motors Diesel Division (GMD) London -built F7B and F9B differed from their Electro-Motive Division (EMD) La Grange-built counterparts and have their own unique attributes.

    in 1971 and remained in dual freight-passenger service but with reduced 65 mph gearing. Then in 1979, the five units still equipped with steam generators were renumbered 1961-1965 for transfer to VIA Rail. Of the five units transferred to VIA (renumbered by CP to 1961-1965, although 1961 was briefly numbered 1931 until a numbering conflict was discovered), most remained in CP Rail paint but were gradually repainted over time.
  • Page 6: Break-In

    BREAK-IN Don’t break into anyone’s layout room to steal their B-units. Or any units for that matter! We’ll send some of our front-office staff after you if you do. Don’t believe us? You should hear the threats we get from Lystra when she doesn’t get her way! So just buy more for yourself.
  • Page 7: Missing Or Damaged Parts

    MISSING OR DAMAGED PARTS With about 300 individual detail parts, the F7B/F9B is a stupidly complex model. But that’s what we’re known for, isn’t it? To prevent inevitable frustration, we recommend checking your locomotive as soon as possible to ensure that everything is where it should be.

    with a small flat screwdriver and then spreading the side frames slightly. Now go looking for the truck end beams that have flown to Jupiter when you stuck the screwdriver in there. Forget it – they are gone. We probably should have told you to take those out first.

    books anyway. Secondly, in order to have functional diaphragms we would have had to make large cuts into the rear of the unit, which would have looked extremely silly once you took the diaphragms off. If you are displaying your F9B locomotive or you have 96”...
  • Page 10: Operation - Dc (Silent)

    OPERATION – DC (SILENT) If your F7B/F9B locomotive is not equipped with a sound decoder, it should function like most other HO scale locomotives. The gear ratio is 14:1 so it should MU (multiple unit) with your existing fleet. Put it on the track. Give it some juice. Watch it go. Wheeeee! In DC, none of the lighting features work.
  • Page 11: Operation - Dc (Sound)

    bought the silent decoder and spent four hours fiddling to install it, fix the bits you broke off, and get all the functions to work correctly, you’ll realize it would have been cheaper and less frustrating to buy the sound-equipped model and just turn off the sounds.
  • Page 12: Locomotive Address

    LOCOMOTIVE ADDRESS Your Rapido F7B/F9B comes from the factory with a decoder address of 3. We suggest if you are using DCC control that you first test that the locomotive responds on address 3. Once you have verified that the locomotive is responding you should assign it a unique address (normally the road number of the unit) before going any further.
  • Page 13: Functions

    Note that if you are listening to your F7B/F9B idling nicely and then you select another engine, your locomotive still thinks F8 is pressed so it will keep idling along. However, if someone else selects your locomotive’s number and F8 isn’t pressed on their controller, the F7B/F9B will promptly shut down.
  • Page 14 “Full Throttle” is even neater when you throttle down, as it allows you to simulate “coasting” which is such an important part of running a real train. When you press F3 again you turn off “Full Throttle” and the engine will accelerate or decelerate to whatever speed step your throttle happens to be on.
  • Page 15: Horns & Bells

    F13 Curve Squeal Let’s face it, the curve squeal has been the greatest success we’ve created in recent years. It’s absolutely wonderful. It sounds wonderful and can be easily applied to any train. Since most yards and terminals featured rather tight-radius curves, it was never possible for anything to SILENTLY go around them.

    for the benefit of anyone who is pairing their F7B/F9B up to a unit that isn’t sound equipped. If you wish to change the default horn, you can do so by changing CV 163. For changing the default bell, change the value of CV 164. Horns Bells •...

    contact ESU. We can even give you their home address if they don’t get back to you. And we’ll provide the noisemaker for you to let them know you are there at 3 a.m. MORE INFORMATION While addressing the features that most modelers will need for normal operation, these instructions have covered just a small number of the many customizable features of your ESU LokSound decoder.

    Keep in mind the following: the most common reasons for Rapido locomotives not working are dirty wheels or carpet fuzz/cat hair in the wheels and gears. Please visit our YouTube channel and watch Bobby’s helpful video about how to fix both these issues and get yourself up and running again quickly.
