Ra­dio ga ga

Model Rail (UK) - - The Club Room -

After in­her­it­ing a ‘O0’ gauge lay­out, I ex­pe­ri­enced dif­fi­culty main­tain­ing re­li­able op­er­a­tion. This was be­cause of the usual prob­lems: loose con­nec­tions, dirty track and en­gine wheels, and poorly fit­ted fish­plates. All of th­ese fac­tors pre­vented enough power or elec­tric­ity from reach­ing the mo­tor, which drives the lo­co­mo­tive. It seemed to me that the an­swer was a lo­co­mo­tive that car­ried its own power sup­ply, and that a bat­tery was the best way of go­ing about it. So I raided my old toy­box and lib­er­ated a bro­ken ra­dio-con­trolled car. I re­moved the cir­cuit board and wiring and in­stalled it within the lo­co­mo­tive. I now have a ra­dio-con­trolled lo­co­mo­tive that can run, de­spite the above prob­lems.

Please note: Us­ing elec­tri­cal com­po­nents that are not specif­i­cally tai­lored for model rail­way use can be dan­ger­ous. Al­ways seek ad­vice from a qual­i­fied elec­tri­cian be­fore at­tempt­ing any project sim­i­lar to the above. Be­low: Kenny has used four AAA recharge­able bat­ter­ies to keep the lo­co­mo­tive run­ning.
