DCC Doodlebug slow speed

[OldProfessor]

My MA&PA Doodblebug with DCC has a very slow top speed. Is this due to the gearing of the motor or the decoder? I replaced the Decoder on an E60CP and it ran much better. That decoder was marked RoHS H601X# PCB01 REV-B. Will replacing the decoder on the Doodlebug improve performance?
