Watch Commander David McGinley teamed up with his wife, Fiona, to collect toys from colleagues and members of the public.
After a reasonably slow start to collections, things "exploded" in December and toys piled up to be delivered.
The donations became so great that David and Fiona called in a favour from a local vehicle rental firm who provided a van free of charge to help with deliveries.
The toys have now been handed over to local voluntary group, i58, who will distribute them to children across the area in time for Christmas.
David, who organised a similar toy-drive last year, said: "We thought we donated quite a lot of toys last year, but this year we received three or four times as many.
"The people at i58 were gobsmacked and very appreciative.
"We were able to fill the van from floor to roof and had about 15 or 16 trollies full of toys.
"I'd like to say a big thank you to the people at Arc Fleet Services, who provided us with transport free of charge.
"They made things a lot easier for us."
David and Fiona were aided in their efforts through friends and colleagues ditching their Secret Santa plans and donating cash for more toys to be purchased.
They were also helped by nearby business, Arc Fleet Services, who provided complimentary transport to help with the mammoth donation.
The firm's Managing Director, Ian Moffat, said: "We were delighted when the call came through from the local fire station to supply a van to help deliver the donated toy collection to local children.
"All of us should be proud of the community work the fire service does all year round. White Watch are a great team and an asset to Inverclyde.
"Throughout the COVID-19 pandemic, Arc Fleet Services has supported local charities by suppling vans free of charge to help with the distribution of food parcels to the most vulnerable citizens across Inverclyde."
