LocoFi™ at work in Tyco

Tyco making its run at the National Train Show, 2018, Kansas City, MO. Yes, LocoFi™ can bring it to life too!

(Tyco, GP20, Santa Fe #5628)

Can DDLLHA run on a 9V battery?

How about if you can fit this or a rechargeable battery inside the locomotive itself or in a trailing dummy?

(Walthers, SD70ACe, UP #8325)

Deadrail with LocoFi™ 2 on a 2S LiPo

LocoFi 2 can work at as low as 7V which is ideal for a 2S 7.4V LiPo and more possibility of fitting together with the battery in the loco itself

(Model Power, RS-2, Santa Fe #2099)

European loco? No problem!

Contrary to what looks like, DDLLHA will fit even an older European loco with relatively large motor and very little internal space.

(Roco, BR 215)
