Confirmed: the MARC Camden Line is slower than the B&O was in 1893. Looking at a copy of Harwood's _Impossible Challenge_, I see that expresses made the Baltimore–Washington run in 45–55m, with locals down to 1h30m. Today, all the MARC trains are scheduled for over an hour.

@SolarpunkVC The tank enjoys better visibility for the driver (and under safety rules, needs ground guides when it is being moved in tight quarters).
From Mastodon: it is unfair to compare a modern pickup truck to a tank because the M1 Abrams battle tank has better forward visibility and is less likely to run over our kids than a street legal consumer truck.
