Menards isn't going to mop the floor with Lionel. Menards has a limited selection of rolling stock, a line of structures and an incomplete line of tubular track. Menards has had their share of quality issues, it just they're $20.00 failures for rolling stock and around $100.00 failures for structures. I'll grant that Menards simply replaces an item rather than repair.
Lionel still has the name recognition, distribution and product selection.
Disclaimer: I own no Menards train products and no Lionel O Gauge.
