REBUILT GMD-1 LOCOMOTIVE PRODUCT GUIDELINES

Thank you for purchasing this model of CN’s rebuilt GMD-1… The One With The Stripes. 

All you modern-era model railroaders bugged us for this version since the first day we 

announced we were making a GMD-1 back in 2012. We are certain you will not be 

disappointed. We have tooled all three rebuilt GMD-1 series – the 1400s, the 1600s, 

and the 1430-1444 series of retrucked 1600s. 

If this is your first Rapido locomotive, well hello! It’s nice to meet you! We must say you 

are looking particularly handsome today. And we look forward to you owning many 

more Rapido products in the future. This manual is full of useful and interesting informa-

tion for you to get the utmost pleasure out of your GMD-1 model. Did we mention how 

handsome you are? We hope you will take the time to read it, enjoy our witty yet ac-

cessible humour, and perhaps make a life-long friend. Someone as cultured, classy and 

elegant as your kind self only deserves the best that the model railroad industry has to 

offer. 

If you are a returning customer, just put the darn thing on the track, note the ditch lights 

are on F6, and don’t burn it up with a cheap DC controller.

As always, if there is anything amiss with your GMD-1 please do not hesitate to con-

tact us. We stand by our products 100%. The best way to contact us is through email 

([email protected]) but you can reach us by phone or Canada Post as well.

Please do not send a faulty model back to us without first getting authorization. If you 

bought this model in 2017, stuck it under your layout, died 30 years later, had your 

family sell it in an estate sale, and it is being opened for the first time by its new owner 

in 2055… Don’t call us. We’re all retired and living the good life at Joey’s Yak Farm and 

Yoga Spa in Cochabamba, Bolivia.
