Lnadships in 1836... possible & consequences

Hey guys

How far back would the 'first' steam engine have to be to have the posability of landships in 1836? and would this be posble without ABSs?

Also what consequences would this have for the world?

I want to change the world as little as possible upto 1836 and they would only have to be prototypes, preferably done by the Brits, if possible.

Thanks :)
