Has anyone tried adding a flanged drive wheel instead of the blank wheel on the LGB Crocodile locos? Will the plastic drive side rods handle the added stress? Just wanting to make a more realistic loco. Other locomotives have longer wheel bases with all flanged drive wheels as steam locos.

On my version the powered flangeless center wheels never touched the rails so all traction is from the geared outer wheels. So essentially only 2 out of 6 axles are powered. I switched the flanged wheels to the geared center axle and added new flanged wheels to the inner axles. Initially I experienced derailments even in R3 curves so I cut away some of the insulation in the wheel centers to give the inner axles some side play. Works well on R3. I guess all traction is on the two geared axles per truck and the inner axles are carried along by the side rods without much force being transferred.

Should work, what will you increase your minimum diameter / radius to? (when replying please indicate radius or diameter)
I have one slip switch which has R2 radius, but my yard switches are all R3 and main line switches are R5 as are most large curves on my layout are 5' radius. Only problem is I haven't been able to locate a couple of replacement (additional) sets of wheels yet.
