1. Read this: https://gaming.stackexchange.com/questions/274911/how-do-i-delay-a-command
2. Adapt it to detect when a minecart passes over a specific kind of block
3. Make minecarts stop for X seconds when they pass over the specific kind of block (Redstone ore?) — constantly teleport the minecart to its current coordinates??
4. Stop teleporting the minecart to itself, and it should continue

Can you crack it?

Do the commands need to be active all the time, and work for any minecart that passes over redstone ore?

yes. using repeater/chain command blocks.

delay should be 3 seconds (~60 ticks).

you use traincarts

Done.

Total:
5 repeating blocks, 6 chain blocks
Usage:
Iron block to stall, iron ore a few blocks in front to clean up tags.
Run once:
/scoreboard objectives add time dummy
From right <<to<< left:

Repeats (Unconditional, no redstone):
/scoreboard players add @e[score_time_min=1] time 1
/kill @e[score_time_min=DELAY_IN_TICKS,tag=stuck]
/execute @e[type=Armor_stand,tag=stuck] ~ ~ ~ tp @e[type=Minecart,tag=stalled,r=0.4] @e[type=Armor_stand,tag=stuck,r=0]
Bottom:
/execute @e[type=Minecart] ~ ~ ~ detect ~ ~-1 ~ minecraft:iron_block 0 /scoreboard players tag @e[type=Minecart,r=0.1,tag=!stalled] add stall
Top:
/execute @e[type=Minecart] ~ ~ ~ detect ~ ~-1 ~ minecraft:iron_ore 0 /scoreboard players tag @e[type=Minecart,r=0.1,tag=stalled] remove stalled

Chains (all chains set to Conditional, no redstone):
/execute @e[type=Minecart,tag=stall] ~ ~ ~ /summon Armor_stand ~ ~ ~ {Tags:["stucking"],NoAI:1,NoGravity:1,Invisible:1,Invulnerable:1}
/execute @e[type=Minecart,tag=stall] ~ ~ ~ scoreboard players tag @e[type=Minecart,tag=stall,r=0.1] add stalled
/execute @e[type=Minecart,tag=stall] ~ ~ ~ scoreboard players tag @e[type=Minecart,tag=stall,r=0.1] remove stall
/scoreboard players set @e[tag=stucking,type=Armor_stand] time 1
/scoreboard players tag @e[tag=stucking,type=Armor_stand] add stuck
/scoreboard players tag @e[tag=stucking,type=Armor_stand] remove stucking

Problems:
Does not work when multiple carts on the same track (ie if a second cart arrives before the first one leaves, the system breaks.
When the system breaks, it leaves a bunch of invulnerable, invisible armor stands.
-However, this can be fixed by simply exiting the cart or otherwise destroying the cart.

Notes for Andy:
Remember to use minecraft:tp on servers.
Remember to check for invisible characters.
