I recently purchased a Roco 69233 Class 23 steam engine for use on my Marklin layout. The engine was the AC version and had a very attractive appearance and some nice the features such as a weighted metal insert in the boiler and decoder in the tender. When I received the engine , I found out that the smallest turning radius was Roco R3 , 419.6 mm. My layout has some Marklin R1 , 360 mm turns which is equal to Roco R2. Roco, however, does not make AC track and I assumed that the engine was designed to operate on Marklin AC track which would require deeper flanges and the ability to operate on r1 turns similar to all Marklin locomotives. The Roco dealer in the United States would not answer my question on the suitability of the engine for my layout and would accept my return of the engine in its unopened box but would have to charge me for the shipping costs and a 15 % stocking fee.

I would like to know if any one has operated similar Roco engines on R1 Marklin track.
