How to improve the connectivity of Thomas the Tank?

[candersonm2018]

Thomas the Tank has limited connectivity when running on outdoor electrified track. How can the connectivity of Thomas be improved? Running Thomas is a real hit with kids who visit the Gadsden-Pacific Railroad museum in Tucson, Az.

Thanks, Craig A., Volunteer Chairman of Outside G Layout.

Dear Craig,
Try Aerocar's track cleaner.
It's magic!
Have fun!

Any one tired to add additional pickups to Thomas or rolling stock?
