Thankyou fir your response, all the servos are connected with short wires but there are many other wires in the vicinity; track bus, accessory bus and 12v DC. As this o my occurs with 1 loco we are concerned that it may be a spike but confused because the track bus and accessory bus are not connected. Would you recommend bus snubbers on our track bus??
