I am absolutely emphatic about Rapido Trains Inc's newly released FL-9 locomotive and Osgood Bradley coaches. Kudos and salutations to Rapido Trains Inc. for their vision and approach to the N-scale world. I have waited 25 years for a model railroad company to make an FL-9 and accurate New Haven Railroad passenger cars. I was able to run all 15 of the FL-9s on my small temporary layout when I received them in late June 2016. I purchased 10 DC/analog units and 5 DCC/sound units. Then yesterday I received 22 of the Osgood Bradley coaches in the 4 different schemes. I must say that they take a little getting used to and required some small adjustments but that is due to their precision details and scale attributes. The FL-9s were so close together when back-to-back that the buffer plates prevented them from negotiating my curves, which are no tighter than a 13° radius or Kato 248-45 curve. I was able to solve this by removing a buffer plate from one of the engines in each pair. It is rather simple with a pair of needle-nosed pliers and some finesse. I learned quickly that the Osgood Bradleys also couldn't negotiate my, what I thought were wide enough, curves because the bodies and diaphragms were so close when coupled. It was an easy fix because Rapido Trains Inc. uses Micro Trains #1015 short shank couplers. I replaced one end of each coach with a MT #1016 medium shank coupler and the cars negotiated the curves with ease. It was a sacrifice of having a space between the diaphragms but is worth it to me to be able to run them. I wanted to share my findings and remedies in case there were others who encountered the same issues on their layouts. Thanks to the superb engineering these models are easily adapted with a little ingenuity.
