I enthused about it  before - having played with it again recently it's reminded me just how well it  goes - I don't think I've had more fun in any miniature steam vehicle, the  free-steaming boiler and sheer driveability of this one put it in a class if its  own. Pictures below were taken this morning, words are from last time it was  here.\u003c\/font\u003e\u003c\/p\u003e  \u003cp class=\"MsoNormal\"\u003eI can't remember the last time I had this much fun with a  steam wagon, in any scale.\u003co:p\u003e   \u003c\/o:p\u003e  \u003c\/p\u003e  \u003cp class=\"MsoNormal\"\u003eA four inch scale wagon, freelance construction underneath  but worked up to resemble a Sentinel on the outside. It's by no means an  exhibition piece, however the ingenuity of engineering in its construction  combined with the way it drives are remarkable.\u003co:p\u003e   \u003c\/o:p\u003e  \u003c\/p\u003e  \u003cp class=\"MsoNormal\"\u003eSteel vertical boiler with expanded tubes, working pressure  175psi. Feed by twin crosshead pumps, backed up by a substantial double-acting  hand pump. Nabic safety valve. \u003co:p\u003e  \u003c\/o:p\u003e  \u003c\/p\u003e  \u003cp class=\"MsoNormal\"\u003eEngine is constructed around a substantial pair of  locomotive-type slide valve cylinders in cast iron, driving an overhung  crankshaft. Drive by chain to an Albion three speed gearbox – more usually  seen in ancient British motorbikes – then by another chain to the rear axle.  Given the engine has a reverser, this gives three speeds both forward and  backwards, which is quite entertaining.\u003co:p\u003e   \u003c\/o:p\u003e  \u003c\/p\u003e  \u003cp class=\"MsoNormal\"\u003eThe engine steams freely and pulls well – the previous  owner recently completed a twelve mile road run with it, which from my own  experience seems not only feasible but likely to be enjoyable. The wagon is  fitted with a powerful hydraulic foot brake, the regulator is coupled up to a  matching pedal on the other side (although you need to remember it's brake on  the right, accelerator on the left, not like your car).\u003co:p\u003e   \u003c\/o:p\u003e  \u003c\/p\u003e  \u003cp class=\"MsoNormal\"\u003e\u003ca href=\"http:\/\/www.youtube.com\/watch?v=B7r6KzeIQY8\" target=\"_blank\"\u003eThere's  a short video of yours truly running around the estate last week on the thing\u003c\/a\u003e  – I rather like the way your legs hang out the bottom, Fred Flintstone-style.\u003co:p\u003e   \u003c\/o:p\u003e  \u003c\/p\u003e  \u003cp class=\"MsoNormal\"\u003eLength 91 inches\u003c\/p\u003e  \u003cp align=\"left\"\u003e\u003c\/p\u003e  \u003cp align=\"center\"\u003e\u003c\/p\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54019158344021,"sku":"6136","price":10500.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/6136-1.webp?v=1779902362","url":"https:\/\/stationroadsteam.com\/products\/4-inch-scale-sentinel-steam-wagon-stock-code-6136","provider":"Station Road Steam","version":"1.0","type":"link"}
