I have a lot of older "blue box" and MDC cars on my railroad. They run well and are sturdy for operating sessions, but the cast-on detail and oversized brake wheels and stirrup steps are a visual problem, These Tichy detail parts are perfect for dressing up otherwise good cars. They are rather fragile, but anyone who works with parts like these understands that.
