Lovely.
I like the train.
With multiples, and the uniform yellow, it looks very railroady.
Kids are so bright and capable.
I too like Playmobil. Remember several years of great play with my young son; pirates, western, knights, trains, civilian kids, divers, boats. A great toy for fantasy , creativity, and story telling. Like trains, each theme creates its own small fantasy world. Enough details to make it come alive.
That rc deisel looks great. My son had / has the old steam tank loco, and his designated lgb stock.
Initially, it seemed pricey, but in the long run, it is great because kids, and adults, stay interested, and, a new piece renews the entire collection.
Still have a small closet full.
