Details and Patterns From Railway Museum

I must admit I really enjoy taking photos of patterns and details. Even if the photographed object is interesting by itself, there is a lot to see when you look at the details.
We have spent the last weekend in the railway museum in Lužná near city Rakovník, in the Czech Republic. For example, the old steam locomotives were so huge and impressive. After taking several compulsory photos of the whole machines, I focused on finding interesting details and patterns.
