Looks like christmas, but it's actually taken sunday easter morning, i.e. today. While we're used to snow in Goslar, this is really not usual.
A RegionalExpress (regional express train, although you don't notice the express part when you're in it) is heading into Goslar station. It's consisting of n-Type carriages, known as "Silberlinge" from the time when they weren't painted and just showed off their stainless steel sides.
It's pushed by the german standard diesel locomotive for just about anything, the class 218. The victory-sign it's exhaust stacks are making is meant to prevent the catenary from getting dirty when used on electrified lines.
