I am looking to build a MOC and want to use drivers either equal in scale the PRR's T1 or larger in scale. I believe BBB XL drivers are still too small, so what is the next best option?
Here are a few I was thinking of:
1) Contacting BBB and trying to get a custom set of deivers made.
2) Contacting the custom siderods guy and getting a custom,set of drivers made.
3) Purchasing Lionel T1 wheels and modifying a few bricks to use them.
1 and 2 will be pricey, but it will be closer to true lego.
3 will add weight, improve traction, and reduce derails at high speed, but will need to modify lego brick.
Other suggestions welcome!
