Well, I think this topic is a good idea. There are many suggestions, but they're chaotically placed on the forum.
Anyway, I already suggested a Tatra T3 tram here in "Rijndam" topic, but it's completely "buried" in there and difficult to find it there. So I'll put it here, so it's easier to find it and I'll try to reformat it, so it has more details and so on.
Description:
A medium sized tram, primarily meant for tram street running service, although it can be used on high speed tracks (in Prague, there are two light rail-like tracks called "tram expressway" or "tram high speed track"). It's design was partially taken from PCC trams, although it has a lot of differences. It's one of the trams, which was constructed in huge numbers and it's considered to be a legend. Many trams of original design are used till nowadays, but some of them were reconstructed, but still are used till nowadays aswell.
List of vehicle specs:
Note: a Prague type of Tatra T3 is used as example for specs. There are some differences between original and modernized Prague version. they'll be mentioned here
Vehicle type: Unidirectional tram vehicle
Manufacturer: Tatra Smíchov
Maximum speed: Original: 65 km/h (40 mph) Modernized: 72 km/h (45 mph)
Length (without couplers): 14 meters (45 ft)
Width: 2,5 meters (aprox. 8ft)
Height: 3 meters (10ft)
Empty weight: 16 tons (35 000 lb)
Doors: 3 (right side only)
Compatible voltage and current 600/750 V DC[1]
Current collection method: Diamond shaped pantograph.
Propulsion mechanism: Original: Brushed DC motor axle-hung propulsion. Modernized: Brushless DC motor axle-hung proplsion
Power regulation: Original: Rheostatic controller (copied from PCC), which is designed to regulate acceleration and to control electrodynamic braking. Modernized: IGBT transistor regulation.
Braking system: Electrodynamic, Mechanical (Used at low speeds and when EDB can't engage for some reason) and Electromagnetic track brake (Emergency use only)
Compatible track gauge: 1435 mm (4ft 8½in)[2]
Headlight type: Two headlights with halogen light bulbs as a light source
Additional lights: brake lights, turn signal lights, reverse lights (reverse lights are rarely used in regular traffic, they can be usually seen used when shunting in depot).
Security system: None [3]
Additional equipement: Emergency brake automatic bell activation (If driver hits EB, the warning bell starts ringing automatically. Used to aid driver when something or someone gets into tram's way and driver hits EB to avoid collision). Digital line number and destination board (Modernized version only). Ability to open only the front door (used for example, when switch on junction won't flip automatically and driver has to go out and flip it manually). Annoucement system. Buttons for passengers to open the door (Modernized version only).
Notable sounds emitted by vehicle:
Original version.
Standing still: Low pitched humming with white noise. (emitted by motor-generator, which powers utilities and cools down rheostatic controller).
Accelerating from stand-still: A few silent clicks (emitted by relays being switched). Loud clicking pop (only if driver stops accelerating early after starting. Emitted by relay being quickly switched off)
Speeding up: A middle pitched humming, which pitch raises when the tram is going faster.
Coasting: Middle loud, low pitched metallic white noise (emitted by wheels rolling on tracks).
Slowing down: Same as speeding up, only pitch of the humming drops down as the tram is going slower.
Stopping: The humming is slowly washed away by motor-generator's sound as the tram goes into stop.
Modernized version.
Standing still: Complete silence
Accelerating from stand-still: A steady high pitched squealing (emmited by IGBT transistors)
Speeding up: Same sound as original version
Coasting: Same sound as original version
Slowing down: Same sound as original version
Stopping: Almost same as original version, only high pitched squealing suddenly kicks in and when tram stops, the squealing goes out and tram goes silent.

Footnotes:
[1]: The Prague version (both original and modernized) primarily runs on 600V DC, but it's able to withstand 750V DC without any harm. This minor tweak is intentional. The manufacturer counted with option, that Prague transport company would raise the voltage in tram's catenary in the future. This actually never happened till nowadays, but this tweak remained in there, if Prague transport company changes it's mind and decides to raise the voltage.
In Metrosim, They can be used in Rijndam tram network, since voltage here is (possibly) 750V DC and this tram can withstand it. They would run on Simvliet light rail aswell, but they're not appropriate here due to other reasons (They're unidirectional, both versions are quite slow for Simvliet light rail, and I am counting for them to be fitted with ATB, and Simvliet light rail is fitted with ZUB).
[2]: Some versions of this tram were fitted with different track gauges. For example: Tatra T3 trams used on interurban tram expressway between Liberec and Jablonec nad Nisou are fitted with 1000mm (3 ft 3 3⁄8 in) gauge. And Tatra T3 trams used in Russian cities or in cities of countries of former Soviet Russia are fitted with 1524mm (5 ft) gauge. I am counting for standart gauge 1435 mm (4ft 8½in) to be used for Tatra T3 in Metrosim
[3]: IRL Tatra T3 has no security system at all (and all other trams in Prague aswell). This tram is meant to be driven by "Driving on sight" style, whereas most of the vehicles in metrosim are meant to be driven in "Security system assisted driving" style.
Yeah, the fact, that Prague trams have no security system installed backfired sometimes. For example, back in June 2018, the driver of Skoda 15T tram on line 16 was going downhill on Ječná street heading to Charles square, driver misjudged the speed and crashed into standing pair of Tatra T3 trams on line 22. Nobody died, but 25 people were injured (including driver of Skoda 15T tram) during crash. The Czech rail safety inspection bureau, concluded the accident as human factor error, and IDK what happened to driver from Skoda 15T, after accident, but I think he recovered from his injuries and possibly got fired from his job.
For Tatra T3, I am actually counting for it to be fitted with ATB in Metrosim.
If you want to make a very fast ride, just disable ATB/ZUB, put trottle to 1.00 and enjoy.

Sorry for my bad English. I am Czech and i am learning English
