I'm new to prewar O gauge so pardon my lack of knowledge. Were these trains made in standard O and 027? I'm having trouble coupling a 2810 crane car to a 2620 search light car. This is according to the coupler arms of both cars being perfectly perpendicular to the track. If there are two gauges, is the automatic coupler height compatible between the two? The crane car sets a bit higher than the search light car. I can get them to couple, but the search light car lifts from the track enough for the light car's roller not to make contact. I could bend the coupler arms, but they look odd and won't operate smoothly.
Thanks...Rich
