Regarding the enthusiasm towards battery powered locos, I've been contemplating switching over to the Deltang system myself for the past week. Prior to your mentioning this system on this forum... I'd never heard of Deltang since the vast majority of US modelers are still in a love affair with track power for some odd reason.
Keep in mind that although your modeling is based on UK themed railways which is foreign to my mind, I've gleaned a ton of useful information from you that may be incorporated into my own railway eventually in one form or another.
In summary, don't stop doing what you do.
