Recent discussions about the WP&Y 2-6-2 #4 returning steam to Como have revolved around the fact that her seized rear trailing truck may not be repaired by the time she returns thus leave her a 2-6-0 for a period of time.
However, there could be worse things that could happen. As we see in this 1890 photo taken at the Como roundhouse, there is plenty of precedent for having 2-6-0's on this particular turntable.
