美国陆军震天动地的越野陆地列车
The US Army's earth-shaking, off-road land trains
2020 — 2022,它一次次回到首页
黑点是上首页(≥ 50 分)的那次投稿,空心点是没冲上去的投稿,点越大分数越高。
导读
这篇文章回顾了美国陆军在冷战时期为北极运输研制的巨型越野“陆地列车”(如 LeTourneau 的多节橡胶轮胎车列),其初衷是向 DEW 线雷达站等偏远站点运送重货。这些庞然大物曾在冰原上轰隆驶过,最终因成本、机动性与直升机/常规车辆等替代方案而未能大规模实用化。
为什么经久不衰:它记录了一个介于工程奇迹与荒诞乌托邦之间的真实项目,配上大量照片,是“疯狂但认真做过”的工业史标本,也让人重新审视技术路线的选择。

Rolligon 类低压轮胎车辆至今仍因环保法规在北极矿区服役。
另一种为极地运输设计的奇特车辆是 Rolligon。这类车辆(今天大多已不用这个名字)至今仍用于加拿大和阿拉斯加北极地区的矿山与油田——动机往往不是雪地/冰面通过性(那和履带车差不多),而是环保法规规定的车辆最大接地压力上限,以避免过度破坏植被。为此存在一整个“低接地压力”车辆世界,在非极地场景通常靠超宽橡胶履带实现。

Another unusual type of vehicle designed for arctic transport applications is the Rolligon: https://jalopnik.com/weird-tech-friday-the-rolligon-for-when-you-want-to-r-1724171889 Rolligon-type vehicles (mostly not under the Rolligon name today) are still used in mine and oilfield applications in the Canadian and Alaskan arctic. This is often motivated less by their snow/ice capability (which is similar to tracked vehicles), than by environmental regulations which specify a maximum ground pressure exerted by vehicles to prevent excessive damage to plant life. There's a whole world of "low ground pressure" vehicles for this reason, although in non-arctic situations they usually achieve this by use of exceptionally wide rubber tracks.
传闻苏联也曾为运输 N-1 火箭研制过类似巨型越野车。
听过一个传说:苏联规划载人登月时,曾考虑在莫斯科制造那个巨型火箭,再经河流运到里海、然后陆路东运至发射场。为此苏联开始建造一台相当大的越野车辆,和文中这些颇相似,但后来放弃了,因为决定直接在拜科努尔就地制造 N-1。那车的残骸据说在网上出现过……不知有人能证实或证伪吗。

Heard a legend that when USSR planned the manned Moon program, one of ideas for how to bring a humongous rocket to Baikonur was manufacture it in Moscow, then move by rivers to Caspian Sea and then move over land east, to the launch pads. For that purpose USSR started to construct a pretty big off-road vehicle - rather similar to what's pictured here, but dropped the project, as N-1 was decided to be built on Baikonur itself. Remnants of the vehicle surfaced somewhere on the Web... Wonder if somebody could confirm or disprove this :) .
补充解释文中未定义的 DEW Line 是什么。
文章没有解释,所谓“DEW Line”即“远程预警线”,是冷战期间在加拿大极北地区修建的一串雷达站,用于预警来自苏联的飞机或部队。

Since it's not defined in the article, the "DEW Line" is the Distant Early Warning like, a string of radar stations in the far northern regions of Canada designed during the Cold War to provide early warning of incoming planes or troops from the Soviet Union. https://en.wikipedia.org/wiki/Distant_Early_Warning_Line
推荐更深入的陆地列车与苏联极地越野车视频资料。
我关注的一位 YouTuber 最近做了一部约一小时的陆地列车纪录片,考据扎实,还包含文章没提到的一些有趣细节。喜欢的话也推荐看他讲苏联“哈尔科夫чан卡”南极越野车的视频,同样好看,也是最初把我引到他频道的内容。

A YouTuber I follow recently put up a ~1 hour long documentary on the land trains [1]. It's well-researched and contains some interesting details not covered by the article. And if you enjoy that, be sure to check out his video on the Soviet Kharkovchanka Antarctic cruisers [2]. It's just as entertaining and what initially led me to his channel.
