"We made it!"
-Connor exiting The Portal and entering the Diesel Supply Yard
The Diesel Supply Yard is a location in Quest 89.
The Diesel Supply Yard was originally a shunting yard infront of a shed in Tankopia, but once the diesels came, they used it to store their supplies and troops.
Connor and his friends arrived at the supply yard via The Portal. They were almost spotted by some troops! Luckily, Connor hid behind some trucks and the others hid in a shed. Once the troops left, everyone except Gold Leader split up to find 089. The latter appeared with his girfriend, Lady, to meet up with Gold Leader. The three headed off for Diesel Headquarters II, as a lone troop secretly watched.
