Well now that I have the Proto 2000 SP Daylight E-8/9 I’d like to add a few passenger cars to it. BLI and MTH are really nice cars, BUT… they cost quite a bit of $$$ That takes us down to second line cars. Con-Cor has as lot of 72’ smooth side passenger cars. I don’t think any of them come with the diaphragms. Cost: ~$30. Athearn’s cost about ~$16.00, but only has two cars available in the Daylight livery. Again no diaphragms. I have 30 inch minimum cures. Has anyone used either the Con-Cor Daylight Passenger cars abd how did you like them
