Please watch at least a portion of this video. It's a modular train show in the UK (running coarse scale tinplate). What are the black metal 'braces' under the tracks holding these loops securely spaced & together? Are they readily available? What are they called? Will they work on Lionel tubular tracks? Thanks.
