How would I add multiple carts? [Rollercoaster node system]

Hello! I have a rollercoaster node system that drags a part around nodes, Something’s stumped me though, How could I add multiple carts to the system? Here’s my current code:

local TweenService = game:GetService("TweenService")
local Model = script.Parent.Parent

local Number = 1
local MaxNumber = 33

while wait() do
if Number == MaxNumber then
	Number = 1
else
	Number += 1
end

local PartToMoveTo = "Part"..Number
local PartSpeed = script.Parent.Parent.Parent.Nodes[PartToMoveTo].Speed.Value
local PartWait = script.Parent.Parent.Parent.Nodes[PartToMoveTo].WaitTime.Value

if PartWait ~= 0 then
	wait(PartWait)
end

local TweenService = game:GetService("TweenService")
local Resize = script.Parent
local Goal = {}
Goal.CFrame = script.Parent.Parent.Parent.Nodes[PartToMoveTo].CFrame

local TwInfo = TweenInfo.new(
	PartSpeed, -- Time
	Enum.EasingStyle.Linear, -- EasingStyle
	Enum.EasingDirection.InOut, -- EasingDirection
	0, -- RepeatCount (when less than zero the tween will loop indefinitely)
	false, -- Reverses (tween will reverse once reaching it's goal)
	0 -- DelayTime
)

local Tween1 = TweenService:Create(Resize, TwInfo, Goal)
Tween1:Play()

Tween1.Completed:Wait() 
 end

Thank you in advance!
